A. applied B. nomothetic C. basic D. generalization Question 5 of 20 5.0/ 5.0 Points A researcher hypothesizes that verbal criticism and aggression among coworkers increase as frustration increases.

In this example the dependent variable is: A. frustration level. B. verbal aggression and criticism. C. the number of people in a group. D. amount of work completed. Question 6 of 20 5.0/ 5.0 Points If a researcher was weighing white mice and used an ordinary bathroom scale, this measure would be expected to show: A. floor effects. B. ceiling effects. C. both good reliability and good validity. D. good validity but poor reliability. Question 7 of 20 5.0/ 5.0 Points Why is it important to represent the diversity of the culture in psychological and medical research? A. Because the risk associated with research should be shared equally. B. Because findings in one group may not apply to other groups. C. Because Title IX dictates equal availability of research opportunities. D. Because every group is required to fund the research, every group should be allowed to conduct the research. Question 8 of 20 5.0/ 5.0 Points In a study of weight control, in which the proportion of fat and carbohydrate intake is varied across conditions and subsequent weight loss is measured,: A. fat is an independent variable.

A. stimulus B. behavioral C. organismic D. participant Question 13 of 20 5.0/ 5.0 Points In the development of a new measure of job satisfaction, the researchers give the measures twice to the same participants at 6-month intervals in order to establish: A. test-retest reliability. B. interrater reliability. C. a correlation coefficient. D. social desirability. Question 14 of 20 5.0/ 5.0 Points Feelings such as sadness, stress, and fear can be studied by: A. operationally defining a set of procedures for manipulating those feelings. B. practically defining a set of procedures for manipulating those feelings. C. operationally defining a set of procedures for directly observing those feelings. D. They cannot be studied effectively. Question 15 of 20 5.0/ 5.0 Points Researchers commonly safeguard confidentiality by: A. changing the names of participants. B. using participants that live far away from the research center. C. using numerical codes for participant identification. D. using initials only. Question 16 of 20 5.0/ 5.0 Points If a broken clock (i.e., stuck on the same time) is consulted every hour on the hour, it will A. yield a reading that is valid. B. yield a reading that is valid but not reliable. C. yield a highly reliable reading, but one that is not valid. D. help a Type-A personality to relax. Question 17 of 20 5.0/ 5.0 Points A researcher wants to develop a measure of test anxiety with high internal consistency reliability. It would be best for her to have the measure consist of: A. one item. B. ten items. C. twenty items. D. Item number is not important to internal consistency reliability. Question 18 of 20 5.0/ 5.0 Points A researcher measures the variable of a living situation as follows: 1=urban; 2=suburban; 3=rural. This is an example of a(n) __________ scale.
