Collaborative Learning Community: Video Game Violence and Aggression

We choose an experimental design. 

Randomly select Junior High School students who have never play video games and expose them to 3-5 hours of video games every week for a month. These will be all well-behaved students who are even-tempered, well-behaved students. The random selection will be done from their student performance, from prior and current history. The sample size will consist of an equal number of boys and girls in the study, so gender will not be a factor. They should all be the same age, grade level, and so on. The only difference will be Whether or not there will be a change in their behavior, measure after the fact. Sample size can be 70, 35 control group 35 experimental group The control group will expose fun non-violent video games. The experimental group will only receive violent video games.

Hypothesis: Violent video games can cause aggressive behavior

Null Hypothesis: Violent video games can cause aggressive behavior

Independent variable is the type of video games

Dependent variable behavior after playing video games

 

Using a between-subject design, independent sample t-test, critical value p = .05.  If there was a significant difference between the two groups, suggest that violent video games do indeed cause aggressive behavior.
