   Question

   Which of the following 2 statements is/are correct for discriminant analysis as a follow-up to MANOVA?

   I. Discriminant analysis predicts the category of experimental manipulation from the dependent variables of MANOVA
   II. With discriminant analysis we decide which of the 4 tests of MANOVA (Pillai’s trace, Roy’s Largest Root, Wilk’s Lamda and Hotellings Trace) to use.

   
   
   1. FALSE: Both statements I and II are correct
   2. FALSE: Both statements I and II are incorrect
   3. TRUE: Statement I is correct, while statement II is incorrect
   4. FALSE: Statement I is incorrect, while statement II is correct
   
   

   Solution

   The  statement “Discriminant analysis predicts the category of experimental manipulation from the dependent variables of MANOVA” is correct. Discriminant Analysis turns around the situation of MANOVA. The dependent variables of MANOVA are used as predictors in discriminant analysis, while the independent variable of MANOVA (the experimental manipulation) is the dependent variable.

   The  statement " With discriminant analysis we decide which of the 4 tests of MANOVA (Pillai’s trace, Roy’s Largest Root, Wilk’s Lamda and Hotellings Trace) to use" is incorrect. Discriminant analysis has nothing to do with it.

   
   
   1. False
   2. False
   3. True
   4. False
