Factorial Anova- Results Essays Factorial Anova- Results Essay Factorial Anova- Results Essay 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, (5) = 4. 70, p gt; . 05 and alcohol amount and lighting type interaction effect, (5) = 2. 58, p gt; . 05. There was a significant main effect of type of lighting on attractiveness of chosen mate, F (1, 25) = 23. 42, p lt;. 001, partial = . 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).

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. 4, SD = 8. 42) compared to the case in which they drunk 4 pint (M = 44. 00, SD = 8. 31). There was a significant interaction effect between the type of lighting and the amount of alcohol drunk, F (3, 75) = 22. 22, p lt;. 001, partial = . 47. This indicates that type of lighting had different effects on chosen mates’ attractiven ess score depending on what amount of alcohol was drunk. To break down this interaction, simple effects analyses were conducted. As can be seen Figure 1, the effect of alcohol amount on attractiveness scores of chosen mate was similar in bright and dim light.This mean that in both dim and bright light, people chose least attractive mates when they drunk 6 pints alcohol. Moreover, they chose most attractive mates when they drunk none or 2 pints alcohol in both dim and bright light. On the other hand, the effect of lighting on attractiveness scores of chosen mate was different at the four different alcohol amount. Results indicated that when people drunk none alcohol, they chose similarly attractive mates in both lighting. However, attractiveness score of chosen mate was lower in the bright light than the attractiveness score of chosen mate in the dim light when people drunk 2 pints alcohol.Moreover, people chose less attractive mates in the dim light compared to bright light when the y drunk 4 or 6 pints alcohol (See table 2).
