The researchers thought that the omnibus F test was not telling the whole story. They looked back over the week and created a new design based on their initial hypotheses. Since happiness was measured at the beginning of the study and at the end of the study, they created a second factor (pretest, posttest).

Using this "mixed-model" factorial ANOVA design, they set about testing whether the effectiveness of reminiscing strategies looked different at pretest and posttest. Results indicated:

• No significant main effect of condition (imagery, memorability, control), p > .05,eta-squared =0.00
• A significant main effect of time (pretest, posttest), F(1,59) = 4.70, p < 0.04, eta-squared= 0.07
• A significant condition X time interaction, F(2,59) = 3.22, p < 0.05, eta-squared =0.10

Question 17 of 394 Points

How would you interpret the main effect of time?

• A.

Averaging across time, there were significant differences in happiness across the three conditions(imagery, memorabilia, control)

• B.

Averaging across condition (imagery, memorabilia, control), there were significant differences in happiness across time

• C.

Averaging across time, there were significant differences in happiness between every condition (imagery, memorabilia, control)

• D.

Averaging across condition (imagery, memorabilia, control), there were no significant differences in happiness across time
