   Below is the SPSS output of a study of the effects of worked examples (WORKED with 0 = no worked examples and 1 = worked examples) on students’ performance on a test (TOETS rated with a grade of 1 - 10). This also distinguished the prior knowledge students had about the topic (FORKNOWLED with 0 = little prior knowledge and 1 = a lot of prior knowledge).

   

   Which statement about impact testing is correct ($\alpha$ = .05)?

   
   
   1. FALSE: There is no main effect of FORKNIS on TOETS, but there is a main effect of WORKED.
   2. FALSE: The effect WORKED is the same for the two categories of FOReknowledge.
   3. FALSE: None of the above statements is correct.
   4. TRUE: There is a main effect of FORKNESS on TOETS, but no main effect of WORKED.
