Document Summary

Overall, men rated the movie sig. higher than women: whether the movie played on a weekday or weekend had no sig. effect, men rated the movie higher regardless of when it was seen. Tests of between-subjects effects p < 0. 001 sig. F= (cid:3279)(cid:3281)(cid:3280)= (cid:2870)(cid:2868). (cid:2869)(cid:2874)(cid:2875)/(cid:2869) (cid:3279)(cid:3281) (cid:3280) (cid:2871)(cid:2868). (cid:2871)(cid:2871)/(cid:2870)(cid:2868)=(cid:883)(cid:885). (cid:885) Interpretation for sig. interaction: p= . 002 < . 05 sig. A sig. interaction qualifies the main effects: results of the main effects are true in some circumstances but not in others. F= (cid:3279)(cid:3281)(cid:3280)= (cid:2872). (cid:2869)(cid:2874)(cid:2875)/(cid:2869) (cid:3279)(cid:3281) (cid:3280) (cid:2871)(cid:2868). (cid:2871)(cid:2871)/(cid:2870)(cid:2868)=(cid:884)(cid:890). (cid:883)(cid:885) (cid:2871)(cid:2868). (cid:2871)(cid:2871)/(cid:2870)(cid:2868)=(cid:884). (cid:889)5. Note: ss = type iii sum of squares. Sig. main effect of gender: men (m= 8. 2) rated the movie higher than women (m= 5. 5) p = . 113 > 0. 05 not sig. No sig. effect of time: weekday ratings (m= 6. 42) did not sig. differ from weekend ratings (m= 7. 25) Requires further post hoc tests to find out exactly where the differences are.
