   Question

   Below are a number of output tables of a series of ANOVA and ANCOVA analyses of cultural participation, measured at time 1 (culpar_1: before the CJP was distributed) and at time 2 (culpar_2) among the same respondents who can be divided into two groups: a group that did not receive a CJP and a group that received a CJP between time 1 and 2 (a group that already had a CJP was not considered).

   

   How can you test whether the assumption of the ‘homogeneity of regression slopes’ of ANCOVA is fulfilled?

   
   
   1. FALSE: By adding the interaction between culpar_1 and cjp to analysis 2; the F-value of the ‘corrected model’ tests this assumption
   2. TRUE: By adding to analysis 2 the interaction between culpar_1 and cjp; the F-value of the interaction effect between the two tests the assumption
   3. FALSE: By taking culpar_1 as the dependent variable and cjp as the independent; the F-value of the corrected model tests this assumption
   4. FALSE: By taking culpar_1 as the dependent variable and cjp as the independent; the F-value of the interaction effect between the two tests the assumption
   
   
   1. False
   2. True
   3. False
   4. False
