   Question

   A researcher conducts a statistical analysis for main arithmetic (HOOFDRK; 1 = not proficient to 20 = very proficient) with the factors SEKSE (1 = boy, 2 = girl) and type of education (TYPEOW; 0 = basic, 1 = special).

   Using the SPSS output for the effects of SEKSE and TYPEOW, evaluate the following two statements.

   I. There is no significant ($\alpha$ = 10%) interaction effect of SEKSE and TYPEOW on HOOFDRK. II. The percentage explained variance in head math by the model is less than 10%.

   

   
   
   1. FALSE: I is correct, II is correct
   2. FALSE: I is true, II is false
   3. FALSE: I is not right, II is not right
   4. TRUE: I is not right, II is right
   
   

   Solution

   Theorem I is incorrect There is a significant $\alpha$ = 10%) interaction effect of SEKSE×TYPEOW on HOOFDRK, because p = .053 < $\alpha$ = .10

   Theorem II is correct The percentage of explained variance in head counts by the model is less than 10% because $R^2$ =.032 < 10%
