d.) Imagine a few months later, the research team decided to try and replicate their study again. Below you will find a different ANOVA table (illustrating different group means) from what was shown in Question 1C, illustrating the results of the replication study. Determine whether or not there appears to be (i.) a main effect for Factor A, (ii) a main effect for Factor B, and/or (iii.) an AxB interaction effect. Explain how you arrived at your decision regarding the presence/absence of a main effect of Factor A, a main effect of Factor B, and an AxB interaction. Assume any difference between means is significant. As a reminder, Factor A is Memory Training and Factor B is Sleep Deprivation. Replication Study - ANOVA table No Sleep 4-hrs Sleep 8-hrs Sleep Memory Training M=20 M = 12.5 No Memory Training M=5 M = 12.5 M=5 M = 20 e.) Briefly describe the key characteristic/defining feature of a line graph displaying a significant AxB interaction. Briefly describe the key characteristic/defining feature of a line graph displaying no significant AxB interaction.
