On your instruction sheet for question #5 is a set of two SPSS simple effects tests using the split file function. Note that this only looks at two of the simple effects tests rather than all four. The first simple effects looks at the Surprise Reward condition while the second simple effects test looks at the Extrinsic Reward condition.
After looking at the charts above, I interpret it this way:
“Following the significant original interaction, the first follow-up simple effects tests showed significance for the Surprise Reward condition, F(1, 28) = 0.02, p < .001, with higher enjoyment ratings in the Complete Show condition (M = 7.93, SD = 1.28) than in the Incomplete Show condition (M = 7.87, SD = 1.19). Similarly, the second simple effects test showed significance for the Extrinsic Reward condition, F(1, 28) = 14.54, p < .001, with higher enjoyment ratings in the Complete Show condition (M = 7.80, SD = 1.08) than in the Incomplete Show condition (M = 6.13, SD = 1.30)." Is this a correct interpretation of those simple effects tests? Why or why not? Answer options are on the next page. Group of answer choices A - Yes, it is a correct interpretation in its entirety given the significant interaction in the original 2 X 2 ANOVA. There was a significant difference between the Complete and Incomplete Shows in the Extrinsic Reward condition and there was also a significant difference between the Complete and Incomplete Shows in the Surprise Reward condition. B - It is only partially correct. While there was no significant simple effect outcome for the Extrinsic Reward condition (with those in the Complete Show finding the show equally enjoyable as those in the Incomplete Show), there was a significant difference within the Surprise Reward, with participants finding the show more enjoyable in the Complete Show condition than in the Incomplete Show condition. C - It is only partially correct. While there was a significant simple effect outcome for the Extrinsic Reward condition (with those in the Complete Show finding the show more enjoyable than those in the Incomplete Show), there was no significant difference between the Complete and Incomplete Show conditions within the Surprise Reward condition. D - No, it is incorrect interpretation in its entirety given the significant interaction in the original 2 X 2 ANOVA. There was no significant difference between the Complete and Incomplete Shows in the Extrinsic Reward condition, but there was a significant difference between the Complete and Incomplete Shows in the Surprise Reward condition. E - It is incorrect to run simple effects tests at all. Since the original interaction was not significant, simple effects are not required for the interaction of Reward X Show conditions.
