Question 1

Based on the following information identify what type of factorial design is being described and how you reached your conclusion: Dr.Ames is interesting in examining the role of sex (male and female)and social interest (introvert,extravert,and ambivert)in matching romantic partners.

Answer 3

The information provided suggests a 3 × 3 × 2 factorial design because there are three independent variables.All variables are able to be manipulated.The first variable has three levels,the second independent variables has three levels,and the third variable has two levels.
