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. The main effect is statistically significant, but is not likely important. b. 30% of the variance in aggressive behaviors can be explained by the interaction of familiarity of toy and type of toy. c. The main effect is statistically significant and important. d. 0.3% of the variance in familiarity of toy can be explained by aggressive behaviors
