Correlations between movie, video game and societal violence are inconsistent over time, according to a recent meta-analysis.
Christopher J. Ferguson, PhD, chair of psychology at Stetson University, performed statistical analysis of bivariate correlations between movie violence and levels of graphic violence and societal homicide rates. Partial correlations were calculated with median household income, population density, real gross domestic product and youth population levels. Time series analysis was examined to investigate potential trends.
