Question

Quizplus · Accepted Answer

Factorial designs involve manipulating multiple independent variables to study their combined effects on the dependent variable. This allows for the examination of possible interactions between the variables, which cannot be accomplished in a study with only one independent variable. Confounding variables are unwanted variables that may affect the dependent variable and are typically controlled for or eliminated in experimental designs. Context variables refer to situational or environmental factors that may affect the outcome of a study but are not manipulated by the researcher. Therefore, the best choice is independent variables (B).
