Question

A researcher designed an experiment manipulating four independent variables. What design is most likely described?

a) None of these describe the design
b) 2x4
c) 4x4
d) 2x2x4x3

Answer 1

The design that is most likely described is 2x2x4x3.

Step-by-step explanation:

The design that is most likely described is d) 2x2x4x3. In this design, the researcher manipulated four independent variables, resulting in a design with four factors. Each factor has multiple levels, resulting in a 2x2x4x3 design. This means there are two levels of the first factor, two levels of the second factor, four levels of the third factor, and three levels of the fourth factor.
