You want to see if violent videos games have any effect on aggression for middle school boys. So, you get a sample of 50 middle school boys, then you randomly assign 25 of them to play a violent video game and the other 25 of them to play a non-violent video game (for this problem let’s ignore the potential ethical problems of assigning young kids to play violent games). Then you compare the two groups of boys to see if they differ on aggression, which you measure as number of pushes, shoves, kicks, or punches they do to other children in one hour on the playground. What kind of hypothesis test do you think would be appropriate for this study?
a. One-Sample z-test
d. Related-Samples t-test
b. One-Sample t-test
c. Independent-Samples t-test
