Question

A parametric analysis

A) requires a manipulation of the dependent variable.
B) is a means of determining the level of internal validity.
C) requires a manipulation of levels of the independent variable.
D) requires an analysis of the aversive elements of an intervention.

Answer 1

A parametric analysis requires a manipulation of levels of the independent variable. In ideal experimental design, the independent variable is manipulated to see how it affects the dependent variable.

Step-by-step explanation:

A parametric analysis requires a manipulation of levels of the independent variable. In ideal experimental design, the independent variable is manipulated to see how it affects the dependent variable. The researcher measures the changes that are produced in the dependent variable based on the different levels of the independent variable.
