Anderson & Bushman (2001) conducted the meta-analysis, Effects of Violent Video Games On Aggressive Behavior, Aggressive Cognition, Aggressive Affect, Physiological Arousal, and Prosocial Behavior: A Meta-Analytic Review of the Scientific Literature, which determined that there was a correlation between playing video games and aggressive behaviors. In a set of 21 controlled experimental studies, Anderson & Bushman (2001) concluded that there was a correlation between playing video games (x) and engaging in the aggressive behavior (y). Table 1 determined that aggressive behavior was measured at r= .19, therefore concluding that the correlation was statistically significant due to a large number of participants that were involved in the research study. Aggressive behavior in conjunction with playing violent video games was tested with 3,033 participants. If there was a smaller sample size (in this case, less than 3,033 participants), the correlation r=.19 may not have been as large or as significant. This result also yielded significant results because r=.19 is positive, rather than negative. In Table 1 it can also be determined that the results displayed significant results because of the homogeneity test. The homogeneity test determined an outcome of x2(32)  23.25, p > .05 (Anderson & Bushman, 2001). It was measured that the p score was 23.25, compared to the normal value used by SPSS and researchers, which is .05. Because the p-value was larger than .05, it yielded significant results for this research study. If the p-value was smaller than .05, it would not hold the same level of significance.

A meta-analysis (Anderson & Bushman, 2001) reported that the average correlation between time spent playing video games (X) and engaging in aggressive behavior (Y) in a set of 21 well-controlled experimental studies was .19. This correlation was judged to be statistically significant. In your own words, what can you say about the nature of the relationship?

Warner (2013) explained that in a result of .19 will fall among the small (r<.10) and the medium (r<.30) and in less than the large (r<.50). This is an indicator that there is a compelling association, but this does not mean there is a causation between aggressive behavior and video games. Because of the insufficient information provided, we must consider every factor that contributes to the research, for example age of the gamer, time spent playing, time spent watching movies of violence, how much the parents are involved in their child’s life, if that person is involved with the wrong group of individuals, their surrounding neighborhood, and even their social and academic intellect. However, there still is a relationship of correlation on the meta-analysis, but does not necessarily means a causation. The meta-analysis shows a significant association on aggressive behavior being affected by playing violent video games, but does not prove or show that it causes the behavior. If anything it does encourage parents to look for more age appropriate video games and limit the access of violent-themed games for their kids (Anderson, C. & Bushman, B., 2001).
