Question

1. Discriminant analysis seeks to identify a combination of IVs, measured at the nominal level, which best predicts membership in a particular group, as measured by an interval DV.

T

F

2. Descriptive discriminant analysis refers to the process of classifying participants into groups based on a combination of measures.

T

F

3. The correlated linear combinations of original variables identified in descriptive discriminant analysis are called discriminant functions.

T

F

4. If the discriminant analysis is being used for purposes of prediction or classification, the goal of the interpretation of discriminant functions is to determine dimensions that serve as the basis for reliably classifying participants into groups.

T

F

5. Discriminant analysis is often seen as the reverse of MANOVA.

T

F

6. In discriminant analysis, the IVs serve as the grouping variables and the DVs are the predictors.

T

F

7. If the goal of analysis is prediction, the researcher would determine the number of dimensions that maximize the differences among the groups in question.

T

F

8. If prediction is the goal of analysis, the researcher might use discriminant function scores in order to describe group differences.

T

F
