12-41) The meta-analysis approach that estimates the overall effect size of a specified independent variable across a large number of studies is referred to as a. combined estimation. b. combined probability. c. combined factorial. d. combined Wilcoxon. 12-42) Tanya is conducting a meta-analysis where she is examining a large number of published studies and calculating the overall effect size for the independent variable that she is studying. This approach is referred to as a. combined estimation. b. combined probability. c. combined factorial. d. combined Wilcoxon. 12-43) When using the technique of meta-analysis, the __________ approach is useful if there is some debate as to whether or not a particular independent variable is statistically significant, whereas the __________ approach is useful if one wants to determine how strong of an effect the independent variable tends to produce. a. combined estimation; combined probability b. combined estimation; combined factorial c. combined factorial; combined probability d. combined probability; combined estimation 12-44) One of the biggest limitations of meta-analysis is that a. some consider the technique to be unethical. b. statistical results may not be available from the published work. c. the technique is only useful in the natural sciences. d. the technique is more philosophical than scientific. 12-45) Meta-analysis techniques allow the role of __________ to be examined, which gives researchers an idea about factors that might alter the relationship between independent and dependent variables. a. MANOVA b. combined probability c. research ethics d. moderator variables 12-46) __________ is an inferential test that allows the researcher to examine differences among means when two or more dependent variables are measured simultaneously. a. ANOVA b. MANOVA c. Pearson r d. Meta-analysis 12-47) Dr. Jenkins is conducting a factorial experiment where he is examining the mean effects of 3 different independent variables on 2 separate, related dependent variables. In order to avoid the problem of increased Type I error rates, Dr. Jenkins should compute a a. series of separate ANOVAs. b. series of separate t tests. c. MANOVA. d. single ANOVA. 12-48) James is carrying out a factorial experiment containing three separate, but related, dependent variables. He wants to examine the means among the various conditions, but he would like to parcel out the variable of socioeconomic status across all of his subjects. Given this multivariate situation, James would probably compute a(n) a. ANOVA. b. MANOVA. c. MANCOVA. d. ANCOVA. 12-49) If researchers are speculating about the pattern of correlations across several variables that would exist if the relationships were causal ones, they would be engaged in the process of a. structural modeling. b MANOVA. c. MANCOVA. d. meta-analysis. 12-50) In structural modeling, researchers often examine the pattern of correlations across variables over time, which is why the technique is sometimes referred to as a. MANOVA. b. MANCOVA. c. path analysis.
