6-51) In addressing the problem of directionality in correlational research, researchers will often use a statistical technique where correlations are calculated across two or more points in time. This technique is known as a. analysis of variance. b. Spearman rank order correlation. c. cross-lagged panel correlation. d. Chi-square test for homogeneity. 6-52) A statistical approach that removes the variance that is associated with a third variable and recalculates the relationship between the two remaining variables is known as a. partial correlation. b. Spearman rank order correlation. c. factor analysis. d. analysis of variance. 6-53) When researchers attempt to describe their results by fitting a straight line through the data according to the linear equation, Y = a + bX, the technique is referred to as a. factor analysis. b. Spearman rank order correlation. c. cross-lagged panel correlation. d. regression analysis. 6-54) In the linear equation used for regression analysis, Y = a + bX, the Y represents the __________ variable and the X represents the __________ variable. a. predictor; criterion b. criterion; dependent c. independent; dependent d. criterion; predictor 6-55) In multiple regression, the prediction of a __________ variable is carried out through the use of two or more __________ variables. a. predictor; criterion b. criterion; dependent c. independent; dependent d. criterion; predictor 6-56) Francine is carrying out a research project where she administers a survey to some of her classmates and then, several weeks later, she administers the same survey to the same group of classmates. Based on this description, it appears that Francine is a. examining the test-retest reliability of her survey. b. carrying out a multiple regression analysis. c. conducting a factor analysis with her data. d. inferring causation between her independent and dependent variables. 6-57) The most commonly used statistical technique for determining the internal consistency of a measurement instrument is referred to as a. analysis of variance. b. Cronbach’s alpha. c. Tukey’s HSD d. multiple regression. 6-58) Professor Mathers is concerned about the degree to which the results from his new intelligence test that he developed correlate with the scores produced by the well-established Wechsler Adult Intelligence Scale (WAIS). Based on this description, it appears as though Professor Mathers is concerned about the __________ of his test. a. concurrent validity b. predictive validity c. face validity d. construct validity 6-59) If a researcher demonstrates that an instrument’s scores do not correlate with established scales that measure dissimilar attributes, the researcher is examining the instrument’s a. concurrent validity. b. face validity. c. discriminant validity. d. convergent validity. 6-60) If a researcher is trying to identify underlying dimensions in a data set such that the values can be organized into clusters, the researcher is using a. analysis of variance. b. discriminant validity. c. test-retest reliability.
