The Fallacy of Hard Tests

Al Feldzamen writes in with a blog post on the fallacious math behind many specialist examinations. "'The test was very hard,' the medical specialist said. 'Only 35 percent passed.' 'How did they grade it?' I asked. 'Multiple choice,' he said. 'They count the number right.' As a former mathematician, I immediately knew the test results were meaningless. It was typical of the very hard test, like bar exams or medical license exams, where very often the well-qualified and knowledgeable fail the exam. But that's because the exam itself is a fraud."

    Ok... the test will be on... girls. Huh? What do you mean that isn't fair?

  2. I had a teacher... by coldmist · · Score: 4, Funny

    in college that gave very hard tests. Intel Assembly class. For a midterm, we had to decipher Object-Oriented Assembly, and decipher self-modifying code. After 3 weeks of introduction to Assembly.

    I got an A, with an average of 58% in the class.

    For the 2-hour final, he got up at the 1-hour point, and yelled: "The test is over. All pencils down." We just sat there dumbfounded for about 10 seconds, and then he said, "Just kidding. I always wanted to do that."

    Ya, a real great pal there!

    Worst teacher I had in college. He didn't last long

    TFA makes sense. Observe:

    News for nerds?: yes[ ] no[x]
    Stuff that matters?: yes[ ] no[x]

    Clearly the editorial process is fraudulent - as this is a multiple choice, it is obvious that guessing tends to count much more than knowledge.

    From this we can conclude one of two things:

    1) Zonk is bad at guessing
    2) The author is speaking out of his ass

    Tempting as it is, I am going to stick with 2... But I could, of course, be guessing.

    Having done experiments on MBA students

    See, I KNEW they were good for something. Let me guess, the reason you opted for MBAs over mice is that there is far less protests when you do cruel medical experiments on the MBA students than with mice, correct?

    A test on girls isn't fair because no matter what answer you give, it'll be wrong.

    No. I think what he was trying to say was that no matter what, you'd never score with a girl. ;)

    Well, as a (happily) married man and considering the 6 point odd billion global population, I'd say it isn't quite impossible to score with a girl. You just have to learn that there is no correct answer, especially on multiple choice. ;)
