Question

1. You are studying male dominance and how it is influenced by the effect of facial hair, the effect of clothing type, and the effect of facial expression.

What type of factorial design is this (think 2x2, 2x3, 3x3, 2x3x3, etc.)?

2. You are studying male dominance and how it is influenced by the effect of facial hair, the effect of clothing type, and the effect of facial expression.

How many conditions are there?

Answer 1

1. In this representation, the number of numbers (in our case 3, facial expression,facial hair, clothing) ) signifies how many factors there are and the number values tell you how many variations/variable are there in each factors. In our case I have assumed these many variable against each factors:

• Facial hair : (Yes or No) : 2 Variables
• Clothing : ( Summer or Winter) : 2 variables
• Facial expression : (Happy, Sad, Neutral) : 3 variables.

So our factorial design will be of (2 X 2 X 3) . In case we consider clothing has 3 variables (summer, winter and spring) then our factorial design will be (2 X 2 X 3)

2. Conditions is equal to some of all the number in factorial design. In our first case where factorial design is (2 X2 X3) it will be    2*2*3 = 12.

If clothing has three variables then it will be 2*3*3 = 18
