Question

How many variables are there in the factorial research design of 2 × 3 × 2 ?
1. two
2. three
3. seven
4. twelve

Answer 1

Correct Answer - Option 2 : three

There are three variables in the factorial research design of 2 × 3 × 2 

Factorial research design:

1. The study which involves the manipulation of two or more variables is known as factorial design.
2. It includes two major things, factors, and variables
3. Factors are the major independent variables
4. The level is a subdivision of a factor
5. For example in a 3 * 4 factorial design, there are 2 factors. The first variable has 3 levels and the second variable has 4 levels
6. 2*3*2 factorial design has 3 variables. The first variable has 2 levels, the second variable has 3 levels and the third variable has 2 levels. The design is like the following
