Quiz 2 on Chapter 3 DUE POSTED to BRIGHTSPACE by SAT at NOON 1. When using operational definitions, it is important to keep in mind that the operational definition ____. Hint...we discussed this in slides on Monday's lecture. a. must be a direct measure of the construct b. must provide a valid method of measurement but need not be reliable c. should include extra components that are not part of the construct d. is not the same as the construct itself 2. If people score low on one measure and score low on another measure, there is ____. Hint: Think! :-) a. a positive relationship between the two measures b. a negative relationship between the two measures c. no relationship between the two measures d. a cause-and-effect relationship between the two measures 3. You develop a new measure of self-efficacy and you find that people who score high on your measure also score high on a standardized measure of self-efficacy. You have demonstrated ____. Hint: We are still in chapter 3 discussing types of validity and reliability a. concurrent validity b. divergent validity c. predictive validity d. reliability 4. Establishing the reliability of a measurement procedure by using the procedure to measure the same individuals on two separate occasions and comparing the two sets of scores is known as ____. Hint: Reference book and/or slides. We discussed this in class. a. split-half reliability b. internal reliability c. test-retest reliability d. inter-rater reliability 5. Counting the number of times a third-grade student leaves his seat without permission during a 30-minute observation period is an example of using what modality of measurement? Hint: What are they measuring? a. self-report b. survey c. behavioral d. physiological 6. An artifact such as experimenter bias is a threat to the validity of measurement because the ____. Hint: Look up experimental bias in book or slides in Chapter 3 if you are confused. a. outcome measurements may be distorted by the artifact Copyright Cengage Learning. Powered by Cognero. Quiz 2 on Chapter 3 DUE POSTED to BRIGHTSPACE by SAT at NOON b. artifact is an external factor, unrelated to the experiment c. artifact will allow participants to identify the experimental manipulation d. artifact will reduce reliability which will, in turn, reduce validity 7. Whenever an operational definition is used for a hypothetical construct, the question of reliability is important to consider. Hint: This is important to operationalizing our construct. a. True b. False 8. Validity of a measurement procedure is often established with a correlation. a. True b. False 9. How will participants change their normal behavior if they respond to demand characteristics by adopting “the good subject role?” Hint: Review slides on participant reactivity toward the end of Chapter 3 a. They will attempt to produce the data that they think you want. b. They will attempt to make themselves appear better than they really are. c. They will attempt to work against what they think is the research hypothesis. d. They will follow instructions without acting on their suspicions about the study. 10. A strategy for reducing experimenter bias is to ____. Hint, We discussed this, so check book and/or slides :-). a. let whoever designed the experiment conduct it b. increase the sample size c. standardize the experiment d. ensure the experimenter understands the risk of bias
