A variable that is controlled for in statistical analysis
An extraneous variable that systematically varies with the independent variable
A variable that is irrelevant to the study
#20
What is the purpose of statistical control in experimental design?
To manipulate the independent variable
To ensure internal validity by accounting for extraneous variables
