Question

In larger factorial designs, at least one IV has independent groups and at least one has correlated groups known as what?

Answer 1

In larger factorial designs, when at least one independent variable (IV) has independent groups and at least one IV has correlated groups, this is known as a mixed factorial design! Why?

Explanation:

A factorial design is a research design in which multiple independent variables are manipulated simultaneously to examine their effects on a dependent variable. In a mixed factorial design, some of the independent variables have independent groups, meaning that participants are randomly assigned to different levels of those variables. On the other hand, other independent variables have correlated groups, meaning that participants are grouped or matched based on specific characteristics or conditions.

Here is an example to illustrate this concept:

Let's consider a study investigating the effects of two independent variables, A and B, on a dependent variable, Y. Variable A has independent groups, where participants are randomly assigned to different levels of A, such as treatment A1 or treatment A2. Variable B, on the other hand, has correlated groups, where participants are matched based on a specific characteristic or condition, such as age or gender.

In this mixed factorial design, some participants will be randomly assigned to different levels of variable A (independent groups), while others will be grouped or matched based on specific characteristics or conditions for variable B (correlated groups).

This mixed factorial design allows researchers to examine the individual and combined effects of both independent variables on the dependent variable, while also considering potential interactions between the independent variables.

In summary, in larger factorial designs, when at least one IV has independent groups and at least one IV has correlated groups, it is referred to as a mixed factorial design!

Correct me if i"m wrong, i hope this answer is helpful to you! :>
