Margaret was interested in whether playing video games effected personality. From a large number of young adolescents she recruited two groups for her study: those who played video games a lot (more than two hours daily) and those who played only a little (not more than once or twice per week). She then administered a personality test to both groups. She found the personality scores of the youth in the high-frequency video game playing group to be significantly different from the scores of the low-frequency video playing group. Margaret concluded that the frequency of playing video games causes variation in personality. How does Margaret's design either support or fail to support her conclusion? Be specific.
