Quizplus · Accepted Answer

Multivariate analysis of variance (MANOVA) is not a data reduction technique, but rather a statistical method to determine whether there are significant differences between means of two or more groups with multiple dependent variables. In contrast, factor analysis, cluster analysis, and multidimensional scaling are all types of data reduction techniques. Therefore, option B is the correct answer.
