D) neither manipulating the factors of interest nor controlling for factors that are not of interest.

Question

Quizplus · Accepted Answer

Experiments involve both manipulating the factors of interest (independent variables) and controlling for factors that are not of interest (extraneous variables). This allows researchers to establish cause-and-effect relationships between the independent variable(s) and the dependent variable. Without controlling for extraneous variables, it is difficult to determine if any observed effects are actually caused by the independent variable(s) or if they are due to some other factor(s).
