Answer to Question 1

ANS: B, D
An independent variable is a stimulus or activity that is manipulated or varied by the researcher to create an effect on the dependent variable. The independent variable is also called an intervention, treatment, or experimental variable. A dependent variable is the response behavior, or outcome that the researcher wants to predict or explain.

Answer to Question 2

ANS: A, D, E
An operational definition is derived from a set of procedures and progressive acts that a researcher performs either to manipulate an independent variable or to measure the existence or degree of existence of the dependent variable.
