Imagine that we have a 2x2 ANOVA in which the two factors are gender (female or male) and exercise habits. Exercise habits has been dichotomized so that people who exercise 2 or more times per week are classified as exercising often and those who exercise 1 or 0 times per week are classified as exercising infrequently. The dependent variable is body weight in pounds.

Question 2 options:

A main effect

An interaction

None of these

A simple effect
