You are interested in conducting a meta-analysis on whether there is a consistent relationship that shows children's aggression and violence are related to watching violence on television. (a) Would you use a(n) unweighted, fixed-effects, or random-effects model to obtain a summary effect size? Explain and justify your choice with at least two reason for choosing your preferred model. (b) Provide three example moderators that might influence this relationship, one methodological moderator, one demographic moderator, and one theoretical moderator. (c) Finally, interpret what it would mean if you obtained the following results (in the table below).
Specifically, what does the summary effect size tell us, and what might be some of the explanations for the observed summary effect size?

\begin{array}{ccccc}\text { Study } \# & \mathrm{~N} & \begin{array}{c}\text { Effect } \\\text { Size }\end{array} & \begin{array}{c}\text { Moderator 1: } \\\text { Methodological }\end{array} & \begin{array}{c}\text { Moderator 2: } \\\text { Demographic }\end{array} \\\hline 1 & 1,000 & -0.15 & 1 & 1 \\2 & 100 & -0.05 & 1 & 1 \\3 & 50 & 0.28 & 2 & 2 \\4 & 200 & 0.05 & 1 & 1 \\5 & 150 & 0.35 & 2 & 3 \\6 & 400 & 0.10 & 2 & 1\\\hline \text { Summary }& 2,000 &-0.10\\\hline\end{array}
