Question 1 Which one of the following is NOT a suggested way to handle missing data in index construction? a. It is always best to simply exclude any cases with missing data. b. You might assign the middle value to cases with missing data. c. A careful analysis of missing data may yield an interpretation of their meaning. d. You may sometimes have grounds for treating missing data as one of the available responses. e.If there are relatively few cases with missing data, you may decide to exclude them from the construction of the index and the analysis.
Question 2 Item analysis is used for a. index validation b. improving item wording c. improving item variance d. assessing index reliability e. determining whether to use a scale or an index Question 3 Hermione wants to develop a scale measuring love. She wants to include a few dozen judges, or experts, to rate each of her items in terms of how strong each indicator is for measuring love. She should use a. Likert scaling b. Guttman scaling c. Thurstone scaling d. a semantic differential scale e. a Bogardus social distance scale
Question 4 Cho wanted to develop a measure of satisfaction with school life using items to reflect the various dimensions of school life (academics, social life, residence halls). She wanted to have each item measure intensity of feeling by using such categories as "strongly agree" and "strongly disagree." Which approach is best? a. Thurstone scaling b. Semantic differential c. Guttman scaling d. Likert scaling e. Bogardus social distance scale
Question 5 Viktor developed a scale to measure attitudes toward feminism. He discovered a pattern of responses among his items such that if he knew the scale score (the number of items someone agree with), he could accurately predict which items that person agreed with. Which scale type did he use? a. Semantic differential b. Guttman scaling c. Thurstone scaling d. Likert scaling e. Bogardus social distance scale Question 6 Serena wanted to analyze the intersection between two variables-school type (public or private) and school location (urban or rural)-in her study of student values. Which approach should she use? a. an index b. typology c. scale types d. semantic differential e. coefficient of reproducibility
Question 7 External validation is to internal validation as prediction is to a. validity b. reliability c. multivariate analysis d. the best strategy for handling missing data e. the connection between the composite index and individual items Question 8 A Guttman scale is most likely to make use of a. judges b. typologies c. polar adjectives d. ordinal response categories e. the coefficient of reproducibility
