After conducting a two-way between-groups ANOVA to test whether the mean number of aggressive behaviors for preschool children varied based on type of toy and familiarity of toy, researchers found a statistically significant effect of familiarity of toy (p = .03), with an effect size of 2p = .003. Interpret this outcome. a. 30% of the variance in aggressive behaviors can be explained by the interaction of familiarity of toy and type of toy. b. The main effect is statistically significant and important. c. The main effect is statistically significant, but is not likely important. d. 0.3% of the variance in familiarity of toy can be explained by aggressive behaviors
