Factorial Anova- Results
A 4(amount of alcohol: 0, 2, 4, 6 pints) X 2(type of lighting: dim, bright) within subjects Factorial ANOVA was conducted on attactiveness scores of chosen mate.
Mauchly’s test indicated that the assumption of sphericity had been assumed for the main effect of alcohol amount, χ²(5) = 4.70, p > .05 and alcohol amount and lighting type interaction effect, χ²(5) = 2.58, p > .05.
There was a significant main effect of type of lighting on attractiveness of chosen mate, F (1, 25) = 23.42, p <.001, partial η² = .48 (See table 1). Results showed that attractiveness score of the chosen mate was significantly higher in bright light (M = 53.44, SD = 5.82) than in dim light (M = 47.25, SD = 4.49).

There was also a significant main effect of the amount of alcohol drunk, F (3, 75) = 104.39, p <.001, partial η² = .81 Post hoc comparisons using Bonferroni test indicated that attractiveness score of chosen mate was not different when people drunk none alcohol (M = 63.29, SD = 6.99) or 2 pints (M = 63.06, SD = 7.91). However, when people drunk 4 pints or 6 pints, they chose mates whose attractiveness score was lower than they chose after they drunk none or 2 pints alcohol. Furthermore, the attractiveness score of chosen mate was significantly lower when the people drunk 6 pint (M = 31.04, SD = 8.42) compared to the case in which they drunk 4 pint (M = 44.00, SD = 8.31).
