DIF: Cognitive Level: Synthesis REF: Page 144 5. A stimulus or activity that is measured to examine the effect created by the independent variable best describes a(n) _____ variable. a. Independent b. Demographic c. Extraneous d. Dependent ANS: D In quantitative research, the independent variable (intervention, treatment, or experimental variable) is manipulated or varied by the researcher to cause an effect on the dependent variable. The dependent variable (response or outcome variable) is measured to examine the effect created by the independent variable. An independent variable is a stimulus or activity that is manipulated or varied by the researcher to create an effect on the dependent variable. A dependent variable is the response behavior or outcome that the researcher wants to predict or explain. Extraneous variables exist in all studies and can affect the measurement of study variables and the relationships among them. Extraneous variables are of primary concern in quantitative studies, because they can obscure one’s understanding of the relational or causal dynamics within the studies. Demographic variables are attributes of the subjects that are measured during the study and used to describe the sample. DIF: Cognitive Level: Comprehension REF: Page 145 6. The intervention that the researcher manipulates is the _____ variable. a. Independent b. Demographic c. Extraneous d.

Extraneous variables are of primary concern in quantitative studies, because they can obscure one’s understanding of the relational or causal dynamics within the studies. The extraneous variables that are not recognized until the study is in process or are recognized before the study is initiated but cannot be controlled are referred to as confounding variables. Demographic variables are attributes of the subjects that are measured during the study and used to describe the sample. DIF: Cognitive Level: Comprehension REF: Page 145
