Study Finds Gamers Prefer Control, Competence Over Violence
Science News reports on a new study which found that the violence in video games was not a significant contributing factor to players' enjoyment. Instead, the feelings of control and competence the games engendered were closely linked to how fun the players found it. Quoting:
"... the researchers extensively modified a popular first-person shooter video game called Half-Life 2 to have less gore. Half the people in a group of 36 male and 65 female college students were instructed to dispatch adversaries as the original game intended, 'in a thoroughly bloody manner,' says Ryan. The other half was instructed to tag enemies with a marker. 'Instead of exploding in blood and dismemberment, they floated gently into the air and went back to base,' Ryan describes. An extensive survey of the two groups showed that the exclusion of violence didn't diminish players' enjoyment of the game."
Your high school "probability class" didn't teach you enough.
According to this, there are about 228 million adults in the US.
According to this, 40% of US adults play videogames, or about 91.2 million.
According to this, a confidence level of 95% and a confidence interval of 10% can be achieved on a population of 91.2 million with a sample size of only 97.
So, yes, you can draw something useful from that.
