Dr. Raqui computed a two-way factorial analysis of variance with types of aggression (relational or overt) and the type of communication method (email, phone, or in-person) as the independent variables, and the level of self-esteem as the dependent variable. The relational aggression main effect was significant, F(1, 222) = 4.2, p = .001, eta²= .031. Which of the following represents the effect size? A) 222 B) .001 C) 4.2 D) .031

The effect size is represented by eta squared (η²), which in this case is .031. This value indicates the proportion of variance in the dependent variable (level of self-esteem) that is explained by the independent variable (types of aggression).
