Ask Slashdot: Statistical Analysis Packages For Libraries?
HolyLime writes "I'm a librarian in a small academic library. Increasingly the administration is asking our department to collect data on various aspects of our activities, class taught, students helped, circulation, collection development, and so on. This is generating a large stream of data that is making it difficult, and time consuming, to qualitatively analyze. For anything complicated, I currently use excel, or an analogous spreadsheet program. I am aware of statistical analysis programs, like SPSS or SAS. Can anyone give me recommendations for statistical analysis programs? I also place emphasis on anything that is open source and easy to implement since it will allow me to bypass the convoluted purchase approval process."
R is my personal favorite but you're going to have to get down and dirty with some high level programming (scripting). Check out the data import package (you would probably export your spreadsheets to flat txt files and import although the functionality is ever increasing). There's no user interface in this suggestion ... what there is, however, is a massive collection of packages for statistical analysis. Very well maintained, constantly updated and ever expanding.
The other suggestion has a better GUI but is really heavyweight. WEKA has helped me time and time again perform advanced statistical calculations on data sets and it's in Java so runs on just about anything. Their interface occasionally improves too, they now have an explorer that I use to prep data and remove outliers/null data (don't worry, this isn't climate data). It's well documented.
These (probably) require an intermediate data transformation step but are open source and extensively supported. Any examples of what you wanted to do? Simple stuff like standard deviation or complex stuff like principle component analysis (PCA)? I guess if it was just simple stuff, that'd be built into Excel, right? Maybe your problems are simple enough to just need a good macro writer to tackle? Whatever happens, good luck!

I find that libraries carry a lot of common information and not so much uncommon information. This sort of muckery seems to encourage concentration of information into a smaller and smaller realm, constantly sorting out first the never-used, then the minimally-used, to maximize volume of return but minimize the use of the library as a haven for obscure and long-forgotten knowledge. Effectively, like burning some books while not burning other books--removes knowledge.
As with all things, there must be balance. A library where you don't increase holding of more useful texts is less immediately useful; although if you removed all the most used texts, you would have an interesting outcome... the obscure and oft-overlooked need retention, too.

Sage (formerly SAGE?) is an open source mathematical package that includes statistical functions. I wanted to add that to the usual mentions of R, etc.
However, are you sure this is what you want? It sounds to me like your real problem is that you have too much data to store. If you're currently using Excel to process your data, and it has been working except that you are running out of space, perhaps what you really need is a database, like Access. If you want OSS, you can probably try LibreOffice, or engage a local student to design a web based system based on MySQL.

Have you checked what's already available on the institution's computers? Many have SAS and others site-licensed. SAS can certainly do small tasks, but it's the most versatile and powerful, if not exactly friendly and intuitive. If you have to acquire something and don't need heavy duty tools, I'm thinking you might fare well with R, also. It's free, so if it doesn't work out, no problem, and you'll find clues scattered all over the 'net. Also, some academic departments may have favorite tools which might not be exactly what you want but are close enough and you know where to find help.
SAS is a great package but is probably prohibitively expensive. An open source version like R is probably more appropriate.
Hear me out. We deal with about 3 million data-producing elements and track in real-time to near-real-time. We ingest everything into MySQL (via macros, scripts, tools, etc.) and normalize the data on the way in. For analysis we simply query. Those queries may have their outcome displayed in a simple report generator, or (more often than not) via HTML5 Canvas graphs/charts, Cacti graphs, etc. What we're doing doesn't lend itself well to a SAS type solution. If you could use SAS for what you're doing, this probably wouldn't work for you.
Look at the free SPSS work-alike PSPP. http://www.gnu.org/software/pspp/ Sounds like R might be a bit much for your needs.
Depending on the type of "analysis" you might be better off with something like PowerPivot. There's alot that you can probably gleen from your data without doing sophisticated statistics, but instead using PowerPivot to slice/dice/summarize/chart your data in different ways. It is easiest to use if you structure your data in a data warehouse/star schema fashion.
Blue skying the toolset is not gonna work. What output do they want, then figure out what tools can generate that output.
If the most important thing is inserting pretty graphs into newsletters, thats one thing.
If the most important thing is hard core data warehousing analysis (for a library?) thats another thing.
The other thing is what answer do they want? They're just looking for data to back up an unpopular decision or glorify themselves demonstrating their amazing management talents. So figure out what that is (by asking them?) and help them get the data they want. Don't give them a graph of declining circulation if they're trying to emphasize their brilliant leadership. Don't give them a graph of increasing student help, if they're trying to justify downsizing.

Seriously, stick with Excel. You and anyone who comes after you would need to learn whatever statistical package you introduce. That is either overkill for the kind of data you're collecting and analysing, or it's a full time job requiring specialist knowledge for which they should be hiring someone else.
Excel has a few bugs but for the most part it's very capable. Ensure you run the service packs and can install the addons that come with it (analysis pack). Get them to send you on advanced short courses for Excel and Statistics. If there isn't that kind of commitment there's no room for any statistical package.
Almost all ask slashdot stories that are work related can be answered the same way - bad idea: you're already out of your depth and if you can't be bothered to google for the information the project is doomed.

I have grown accustomed to doing statistical analysis using Python and R using http://rpy.sourceforge.net/rpy2
I hate to toe the Microsoft line here, but I'd go with Access in this case.
True, SPSS and SAS are statistical analysis packages, but I think they're far beyond what you're looking for. You haven't mentioned T-tests, F-tests, multi-variable regression, etc. That's what those packages are for, and I doubt your administrators even know what they are.
It sounds like you're after basic aggregation ("how many fiction books were checked out in July?", "How many overdue notices to we have to send out, on average, before they bring the book back?", etc.). Access does these just fine, and the built-in wizards will probably help you get more use out of it. You'll get better ability to select what it is you're counting than you would with Excel (want to know the percentage of books in your collection with more than 100 pages that get checked out more than twice per year? Access will do that easily. Excel... you can can do it, but it's a lot of filtering, cutting/pasting, etc.)
I also place emphasis on anything that is open source and easy to implement since it will allow me to bypass the convoluted purchase approval process.
Sorry to burst your bubble, but if you want good support and easy implementation, you have to look for normal paid-for solutions. Besides, open source is not synonym for free. This is especially true with specialized software or something you want good support for. Open source just means you get the code aswell, so you can implement your own additions (without use of plugins) or change it.
Your point may be valid. But what would really help your validity is mentioning some proprietary products that beat R and WEKA at their own game. Sure, I've used Matlab and it can't be beat in some respects and is heavily supported. But to suggest that just because it effortlessly interfaces with Excel spreadsheets when the person could get by with a simple export in Excel to run their R script on the resulting files? Not worth the cash, in my opinion. I don't go out and buy every piece of software to evaluate it, though. I'm aware of Matlab and Mathematica and have used them quite a bit ... but I still prefer R and WEKA. So, CmdrPony, go ahead and list all the proprietary point-and-click-omg-it-just-works software for our friend here. We're all waiting.
But unless you get an product from a company that is spending money to develop it, you never get good software and good support.
Say, friendo, have you ever heard of Linux? Eclipse? Audacity? PostGRES? VLC?
No one can make both because everything in this world costs money, and developers have to live too. Open source and free software model works well for the likes of Google and Firefox because the developments get paid by money made with advertising. Statistical analysis software, and other specialized software is a different matter.
Can you tell me what advertising model is employed to funnel money through Firefox into Google? I mean, Google makes a competing product called Chrome -- the rendering engines are even different! What in the world are you free basing?

Check out PDL (Perl Data Language). It may not be the most convenient solution but it's free and has a great, informed and responsive user group.

If you're already proficient in Excel, I suggest adding the Microsoft Office data analysis pack if you just need some statistical tools inside of Excel. This adds various ANOVA and regression tools inside of excel using an easily accessible Microsoft add-in (you may need to have your Office installation CD handy). http://office.microsoft.com/en-us/excel-help/load-the-analysis-toolpak-HP010021569.aspx contains the instructions. This will be your best and simplest bet if you just need to look at correlation, covariance, descriptive statistics, histograms, and the like.
Alternatively, you can get pretty complicated with all this other fancy stuff or stay in Excel by using RExcel, a free package that allows R Statistical Package to play nice with Excel as the data input interface.
Cheers!
I read this first as: Statistical Analysis Packages For Liberals. Thinking it was some kind of lie with statistics deal going on...
Anyone with decent recommendations, aside from R's own website, where to do a quickstart when you're a SAS geek?
This blog explains some of the stuff you do in R and as he does it, he compares it to SAS.
Example:
Unlike SAS, which has DATA and PROC steps, R has data structures (vectors, matrices, arrays, dataframes) that you can operate on through functions that perform statistical analyses and create graphs. In this way, R is similar to PROC IML.
And here's an entire book on the topic (although may be difficult to find)!
My work here is dung.
It almost seems like you are not doing statistics as much as creating reports from data.
Maybe you should be using a database instead of a spreadsheet or a statistics program.
The Uber geek way would be to set up a LAMP server and create a webased system.
The more convent way would be something like Access.
You can then use Excel to manipulate the data as needed or the database program.
In the end if you know excel you may want to stick with it. I see people use Excel for databases all the time. Drives me a bit nuts but sometimes what ever works is just fine.

Depending on how large your dataset is, you may have luck using Matlab (or the opensource gnu octave). These programs will let you do *whatever* you want with the data (plotting, correlation, fft, etc).
With at least Matlab, there are some MySQL plugins available that will let you get data out of your database and into arrays rather quickly. And of course, both matlab and gnu octave let you import csv and plaintext datafiles.
Here is the matlab plugin I have used very successfully (and it's open source. No idea if it would work with octave):

You will need some background with math, statistics, and programming to effectively do this. If you don't have the skills, learn them or pay up for some overpriced commercial product...
I love R, but if you want something that looks more like SPSS, you could try the free SPSS clone PSPP:

Typically for simple statistics, I do better staying in Python and using the Numpy package for calculation. Scipy provides a mountain of extra packages, and probably has a nice setup for exactly what you want. Certainly Python with Numpy is free, but I'll bet Scipy could be a free resource for you as well.

if a full stats package is a bit heavy, try python + http://www.scipy.org/

In [3]: scipy.mean(x)
Out[3]: 5.4285714285714288
In [4]: scipy.std(x)
Out[4]: 2.7957693986829897
and if you need more than that you can really delve into its stats submodule http://www.scipy.org/doc/api_docs/SciPy.stats.html.
What is your ILS? Depending on what it is, you may already have access to just about all of what you need there along with Excel. Atriuum from Booksys has wonderful features like you are asking about, record tracking, and it exports to Excel very well. Voyager from Ex Libris had wonderful integration with Access and my boss could pull out some amazing statistics with it.
If you don't have an ILS then seriously look at Atriuum as they are great for the smaller libraries.

You may already have access to the tools you need through their licensing. Also, they may be able help get you going.
OK, this is a horribly shameless self-plug, but hey, it's directly relevant. I started two projects aimed at tracking reference statistics: Libstats, which is PHP-based and open-source. I'm also one of the founders of Gimlet, which is hosted and closed-source, but provides a similar workfow.
If you're looking to spend some time delving in code, Libstats is looking for maintainers -- I'm no longer working in libraries, so it's largely orphaned.

Great package for visualizing data. ez to use. great online videos and training.

What you think is large might be trivial even for OpenOffice/LibeOffice.
Also, the real solution might be to automate data collection and storage in a database. Manipulation would then sort itself out.
If you're at a University, then you should go to the Math Dept and talk to some Statistics grad student or maybe even an econometrics grad student in the College of Business. Heck, there's probably Comp Sci undergrads looking for a project to add to their resume.

Perhaps collecting the data in a standard open source software system would be a helpful first step? http://open-ils.org/
Have gnu, will travel.
I use and like JMP from SAS. They offer a free 30 day demo and I think it does a good job at data visualization and statistical modeling, or as they call it, discovery. It will interface with SAS, R, Excel along with various database packages for additional capability that may not exist in the core product. I found it pretty easy to pick up with a fairly active user base to help get started.
Desk Tracker it maybe to simple of a program for what you need, but I have seen it used and it does work. Even has a report section..
Their product list is here. In particular, I think you would be interested in RapidMiner and RapidAnalytics. WIkipedia has a good overview of RapidMiner.
Video tutorials for both RapidMiner and RapidAnalytics are available on their website. Those videos are a great way to get a good sense of what the product line is capable of. Searching on YouTube will find plenty more that focus on specific use cases and more advanced functionality.
All of their software is dual licensed with a GPL version and closed source license available. GPLed versions of their software also has support contracts available for everything from basic troubleshooting support to full implementation. That includes both Rapid-I itself as well as partnerships with contracting companies in the U.S. and elsewhere. In addition, Rapid-I hosts a community forum that is well run and has active developer input.
I've been using RapidMiner myself for 3 years for smaller projects. I have had occasion to use all of the free resources that I mention above. I have found them all to be very solid. The developers in particular have proven themselves to be knowledgeable and very polite. (IME, that's only to be expected of co-founders who happen to be German. :-) )
Rapidminer http://rapid-i.com/content/view/26/84/lang,en/ has a free, open-source community edition. It has an insanely easy to use, slick, very well designed graphical interface, and there are a lot of nice video tutorials (accessible directly from the help drop-down as well as from the website) for the basic functionality, to get you started. It already contains most WEKA functionality built-in, as well as a lot of other freely available algorithms of te type that you could also implement via R packages / SPS / SASS. It can also interface directly with R via its R extension, should you need any additional R functionality that Rapidminer doesn't have (my guess is you won't for your project). I've had zero problems installing and running it on Ubuntu (from Edgy to Natty) or on Windows (from XP to 7 Pro), have not tried Mac. It also updates itself automagically without snags via its own update mechanism on both of these platforms, it just asks you to check "ok" for the GPL for each module. It has a schweet graphical wizard for importing excel, tab delimited text, csv, whatever and telling it what the headers etc. are, and it also has some repository/database functionality but honestly I haven't fooled with that so I can't comment.
I will echo the support for the open-source statistics package R. R is incredibly powerful, and in the natural sciences it is fast becoming the standard statistics software.
I will also echo the sentiment that, by itself, R is fairly low-level and typically requires at least some simple programming to get what you want.
However, there is a very nice graphical front end for R called RKWard (http://rkward.sourceforge.net/). With RKWard, importing and exporting data, running basic analyses on it (descriptive statistics, linear regression, t-tests, etc.), and producing basic graphs is very straightforward and does not require detailed knowledge of the R language. Plus, RKWard is also a nice development environment for writing R code, so if you want to take your project further, you can easily do so. So, I'd recommend giving RKWard + R a look.
It seems to me that all you need is descriptive statistics (change from last month, mean, min, max, etc and probably graphing). Using a general spreadsheet application like Excel or Calc will do the job just fine. Remember that Excel is designed to support business calculations and what you are asked to provide is exactly that! Using a dedicated statistics software for this task (in your environment) is a waste of resources. Full stop.
However, the solution may not be straight-forward to solve in Excel or any other program. In my experience there are two main reasons:
1. The request for data is unclear.
Why do they "increasingly want data on various aspects of our activities"? It could be that the data you have provided so far has not provided support to decisions. Are the questions they really want answered possible to support with the data you can provide? Meet up with the actual decision makers or at least someone who knows what the statistics are actually used for and ask them WHY they need it. Is it used to support resourcing? Is it used to describe changes? Not even a university administration creates statistics for no reason. Most likely, what they really want to know is a handful of numbers like "change from last month", "overall sum", "hours spent on teaching vs information searches".
Do this with an open mind. You will probably learn that many of the imperfections you see in the details are less important to them. When you know their true needs, suggest a package of data, graphs, free-text report or whatever is suitable. If some parts are easy to provide, be clear about that. If something is more difficult to produce, tell them that it is is possible but time-consuming and costly. Get their buy-in before you spend time on producing the output.
2. The raw data is not optimally formatted for the calculations
First of all, if raw data quality can be improved, do that first. Update forms used for feedback, ask for output in a specific format etc. Then arrange the data and calculations in Excel to make it flexible and easy to read and troubleshoot. The trick is to use structure your data and calculations in Excel in a way that is easy to follow visually and logically. In my experience it is very useful to use different tabs for data entry, data analysis and presentation.
It seems from your examples that your input will come from a variety of sources, both manually entered and output from other systems. To get it into Excel, create separate source data tabs where you can enter or paste your raw data. For each source data tab, create a "clean up and calculate" tab where you rearrange source data and make most of the calculations. If raw data is very far from optimal or calculations are complex you may want to use several tabs or even several workbooks for this. Then create presentation tabs where you present the results from calculations in a useful format.
I'm convinced you are suffering from both these problems. Attack them in numeric order and you are well on your way. And by all means, sign up for a course in advanced Excel that is suitable for your application. Best of luck!

I don't know if anyone else mentioned the Rattle GUI for R. It can import data in a number of formats including .csv and will perform all sorts of common statistics including graph functions. The nicest thing is that as you try out new functions the interface automatically asks permission to download the appropriate CRAN packages. If there is any downside to learning R it is finding one's way through the extensive library of packages--Rattle eliminates this anxiety.
i think R with Rattle would be your best bet. Rattle gives a point and clock interface. Also look at rstudio it has a server version so you can run it in a browser, but its best feature is having the help panel beside the coding panel so you can look up syntax and options.

I've used them all and in terms of engineering and academia, MATLAB seems to be where most theoretical prototyping is done. The license costs for academic/student use are reasonable but it's about $2K for a commercial single seat license. Octave is the MATLAB open source alternative and for most basic functions it does well however it doesn't have the extension packages available that MATLAB does.
My favorite and one I use all the time is "R" because it does have great open source community support and there's not a lot it can't do.
Harrison's Postulate - "For every action there is an equal and opposite criticism"
JMP from SAS, Inc. would be perfect for what you are looking for.
JMP would be a sports car, while SAS is a huge semi truck. It is the most powerful point-and-click stats package you'll come across, ie, no languages to learn. Everything is visual. However, it is powerful enough to have a scripting language that is comparable to a lite version of SAS. SAS, SPSS, R, Matlab are overkill for what you are trying to do, like roasting a marshmallow with a rocket engine. You don't need the enterprise database incorporation, you don't need to access terabytes of data, what you need is a visual explorer of the small dataset you have. (ie, you are not analyzing consumer spending patterns across the U.S, you are looking at at most couple hundred thousand observations).
Coming from someone who sits in front of a computer 8 hour a day looking at data. When you don't know what trends you are looking for and you are just exploring, having a visual interface that will scream "look at me, there's an upward trend" is much more useful than having to worry about whether the proper syntax for proc reg.
Agreed ... odds are, they're not running homebrewed circulation software and someone in the library community has tried to extract metrics from whatever they're using.
Build it, and they will come^Hplain.
As others have said, if you're mainly doing reports, stick with Excel or a database solution. Excel lets you look at your data from a variety of angles (pivot tables, etc), and has usable graphs. As usual, Microsoft has numerical issues, so you may get wrong answers under certain conditions, but hey, it's Excel.
What is it that "anything complicated" means? Fancy graphs? Fancy partitioning/aggregation of data? Modeling and forecasting? Summary statistics? Graphs that aren't fancy, but Excel doesn't provide?
An open source option that I haven't seen mentioned is gretl. It has a reasonable GUI and can make nice graphs (though not terribly customizable), give summary statistics, sample data in various ways, and do basic modeling. (It comes from an econometric world, so has quite a few time series capabilities.) If you need to do some things with time series, it would be helpful. (Though if you don't know what you're doing, it simply makes it easy to shoot yourself in the foot.)
I also work for a (relatively) small academic library, but our campus has free licenses for SAS and JMP. I had to go through hoops to get it (bureaucracy being what it is) but I use SAS all the time for inventory and usage data. It helps that I was a SAS programmer once upon a time, but I love it for its abilities to clean data as much as its statistical chops. Check around campus if you haven't done so already. You may find access to one or both of these to be easier than you think.
I'm a working statistician with a fair amount of (data oriented) programming experience. I can say that R is at least initially not that friendly to use and lacks some of the conveniences of traditional statistical packages SAS, SPSS(PASW), STATA. Initially, I preferred to just use SAS to transform the data and then import the final data into R for analysis. There are some things that R does that SAS does not - usually things that are on the bleeding edge of statistical methods. (The project I was working on involved a rare events logistic regression - available through the Zelig package.) There are some groups that have tried to put a nicer friend end on R though. R Studio and Revolution R both attempt to help with the interface a bit and are either free (R-Studio) or free for academics (Revolution R.)
I think a lot of whether or not R is right for you depends on what kind of analyses you're doing and how you get your data. If all you're doing are basic analyses and the data comes in a form that doesn't require extensive modification then R might appear tricky at first, but will likely fit your needs.
If you do go with R, be sure to check out Rstudio (rstudio.org), which is a very nice front-end for R.
In response to the posters who tell you that R is low quality because it's open source, I can tell you that's nonsense. I have Stata, Matlab, and R on my machine, and access to SAS on a research server. There are times to use each, but all else equal I use R. It's not trivial to learn, but it's a powerful high-quality piece of software, widely used in the statistics community. Whether it's appropriate for your use depends on you and the task. But it's great software.
Sounds like R might be a bit much for your needs.
Agreed. Another good alternative is MYSTAT, the free "student" version of SYSTAT. Note also that many academic institutions negotiate site licenses for SYSTAT, so you might already have the full version available to you.

I suspect that what the original poster is doing is trying to cope with bad management.
Anyone who demands complex statistical analysis from a small academic library is creating make-work that will most likely result in diversion of resources from more meaningful tasks.
Subservience to management hubris is probably being prioritized over service to patrons, or they would have assigned additional staff (some math students, perhaps?) to do this work, and not dumped it on the librarians.
The phrase paralysis by analysis comes to mind....
Not open-source but very easy to generate reports off relation data sources. http://www.yellowfin.bi/
It would help if you provided some more details about what you are trying to do. What sort of statistics re you looking to analyze? or are you juts collecting statistics such as average number saved, variations by month, etc. From your post it sounds like you are looking more for activity statistics than statistical analysis; in which car a stat package would just add unneeded complication to your efforts.
A stat package isn't going to make it any easier to analyze the data; it'll just make it easier to generate results based on large data sets. With Excel, I've found it easier to break down the analysis into separate spreadsheet and then link to get results in one sheet. This cuts down calculation time since you are not dealing with a large amount of data in one worksheet.
I'm a consultant - I convert gibberish into cash-flow.
As I understand your workflow, you need a system that automatically collects data generated by your ILS and makes routine (but good looking) reports out if it, from very explicit instructions that can be audited later. You should consider a system like Sweave. You write a template for the report, plus the explicit code in R for the analysis. And let it run at whatever time or frequency you want. SAS may let you do it, with very expensive products. And SPSS is just a mess. R is miles ahead of them.
As a Perl guy, Python(x,y) has a complete scientific computing package. While Perl and Ruby can do these things, Python(x,y) does it in a slick way.
It is a Windows only package as far as I can tell.
Perl, Python and Ruby can deal with Excel and R but Python(x,y) provides a nice interface for everything.
head over to https://stackoverflow.com/tags/r and put your rant there. surely you'll grab someone's attention...
PSPP is a nice idea, but lacks functionality. SPSS is ridculously priced, even with IBM's "discount" for non-profits.
DeduceR and R commander give you access to the full power of R under R GUI. DeduceR gives you spreadsheet
like data entry and basic stats, and then you can load R Commander for a menu driven interface more advanced
functions.
Were that I say, pancakes?
I am a public health physician and an epidemiologist. I have used excel, SPSS, R, SAS, and python's numpy and scipy. I currently use R almost exclusively. I love it but the learning curve is steep and is probably overkill for what you need. I also agree with the comment above regarding statistical analyses versus generating reports.
Take a look at EpiInfo 7. It was originally conceived for managing data related to disease outbreaks but is quite versatile (data is data is data). It is newly released and FREE from the CDC. The dos version was awesome and revolutionary for public health world wide. The later versions were awful but Epi info 7 is back on the right track. It is available cross platform, can be run off a thumb drive, can create data entry forms, supports double data entry, handles spatial mapping, do basic and not so basic statistics and can pull or push data from an SQL server. If your data is already in a database then this would still be helpful for creating reports, generating descriptive statistics, startifying your data and doing more complicate analyses if needed.
Good luck!
Microsoft has a free add-on to Excel called PowerPivot. Sure, it's not going to be as complex as say SAS, but it's way cheap- if you have Excel, it's free. Search for it, try it out. You'll be up and running in minutes and it may prove powerful enough for your needs. If you're already familiar with Pivot tables, PowerPivot takes it to the next level. It's very SQL integrated, but will work with data from nearly any source, and you can combine data from many differing sources. Good luck :)
Well, why not use RapidMiner? It not only does stats, but also will allow you to do text analysis (data mining). It has an extension to run R as well... It is open source. Here is a link: RapidMiner

Most librarians were probably not math majors, and are unlikely to be expert in statistics. But if you can work your way through the book, you may get enough insight into your data to ask good questions from a local Math department. No doubt some graduate student(s) can get a paper out of it, or at least some applied class project credit.
But if you don't understand what it is you are looking for, you probably won't coax them into figuring out what questions you ought to be asking. So start with the book.
While a free version is on the site, support the work by buying a hardcopy for the library ;>
Businesses use Customer relationship management systems. These tools also provide statistics.
Wait a minute, is your administration want to spy you ? Why they want this data ?

If you want something with powerful analysis and a drop dead easy interface, try Tableau. Not free, but definitely worth the money.
they are meant for modeling data and finding relationships between variables - think finding cross sell opportunities or look-a-like models. What you relay need is a Reporting solution not a modeling solution. Check out Tablue or Qlik or LogiXML.

SAS and SPSS (and other mentioned here like R, Mathlab, Octave,etc) are tools used in highly complicated statistical analyis. I know so, cause my wife has a PhD in Biology, wrote several papers in peer review journals, and has to deal with lots of statistical analysis. Even for her works, she does lots of things with excel and the already mentioned XLStats complement (I believe its something like a set of macros for doing statistical analysis). She will only go to SPSS, Mathlab (other software she uses is Primer-e, Surfer and bit of SAS) when she needs to to more complicated stuff...
I think you are going to complicate your daily task with this buddy. Stick with Excel, LibreOffice, OpenOffice or whatever spreadsheet you want
You might want to take a look at LibAnalytics (full disclosure: I work for Springshare). If you're actually trying to do statistical analysis, then I think others' recommendations will server you better - but if you're looking for a way to track many different sorts of data and generate reports, then I think LibAnalytics would serve you very well.

Convert your entire library system to Evergreen (http://www.open-ils.org), a highly-scalable software for libraries that helps library patrons find library materials, and helps libraries manage, catalog, and circulate those materials, no matter how large or complex the libraries. Evergreen is open source software, freely licensed under the GNU GPL, and is already deployed at major libraries around the world.
With Evergreen, you have better control of your library than you'll get from the various vendor-supported library circulation solutions. Because it is open source, you can implement yourself whatever features you need. Because it is being actively supported and extended by several major libraries, if you do not have the resources to extend the system, you can work with libraries that do have resources who may also be interested in implementing your feature.
Evergreen is being used in King County Library System (KCLS) (http://www.kcls.org), the largest library system in the US by several measures, and the Library Journal's 2011 Library of the Year. KCLS is committed to developing, using, extending, and sharing the Evergreen system. KCLS is collaborating and coordinating the development and deployment of Evergreen with a dozen other major libraries systems around the US and the world.
Here's something that might give you a direction.

For the kind of constant, ad hoc, data nagging your talking about the above would be a good start. Using something like MSSQL Analysis Services with Excel on top.... Or (get ready to feel really dirty) MS Access pivot tables....
I haven't pointed someone toward the Microsoft in a while but if you don't have serious programming chops you're best bet is cubes in Access and they will take you quite far. They are extremely similar to Excel Pivot Tables. If you haven't explored Pivot Tables in Excel, there's a possibility that half your battles will be won there on the data as you currently have it.
A more static but open source solution at the scale of Excel Pivot Tables is OpenOffice data pivot functionality. In fact, you might be able to put something together where OpenOffice Calc sits on top of MySQL! That get's you database, spreadsheet and pivot. Any super serious stats can be handled in R....
Every rule has more than one consequence.
Orange ( http://orange.biolab.si/ ) is an open-source app/framework for data mining, analysis and visualization. It's written in Python so it's as much a framework as an application.
This is not the answer you're looking for... Could you post a reply here with whatever you chose to do?
