Selected Answer: A. Confounding variable Answers: A. Confounding variable B. Dependent variable C. Mediating variable D. Independent variable Response Feedback: Factors that are irrelevant in a study and that can obscure the relationship between the independent and dependent variables are called confounding (or extraneous) variables. A goal of research design in quantitative studies is to control these confounding variables to permit a better understanding of the link between the primary variables of interest—the independent and dependent variables. Mediating variables act like a “go-between” in a causal chain between an independent and dependent variable, and are not extraneous to the inquiry. • Question 2 0 out of 10 points A researcher recruits participants for a study and advises them that their time commitment will be 45 minutes in a single session. Participants are not told at the outset that the researcher plans to collect more data from all participants 6 months later. This might be considered an example of: Selected Answer: C. covert data collection. Answers: A. invasion of privacy. B. exploitation. C. covert data collection. D. maleficence. Response Feedback: The researcher could be accused of exploiting the researcher–participant relationship by returning for further data without telling participants in advance. (In addition, this is an example of lack of full disclosure). This situation is not an invasion of privacy nor covert data collection, and presumably, there was no maleficence (doing harm).
