A researcher is investigating the effects of emotion and gender on cooperation. He randomly assigns participants to one of three conditions: control, guilt, happiness
After inducing one of the three emotions, the researcher measures each participant's level of cooperation in a game, on a scale from 1 to 10.

Men:
Control: 5 4 7 4 3 5 5 6
Guilt: 6 9 7 8 6 7 7 8
Happiness: 8 7 8 9 9 6 8 9

Women:
Control: 6 3 5 5 4 7 6 3
Guilt: 3 7 7 4 8 5 4 6
Happiness: 7 6 9 9 7 8 9 8

Test is significant for main effect of emotion ans score are different for each emotion. But not significant for Men and Women and hence not different across Men and Women.
