PSY-33 Lecture Notes - Lecture 25: Effect Size, Casual Sex, Mental Rotation
Document Summary
Beliefs about personality similarities and differences between men and women. Women more concerned with other people and the social group, being interdependent, and feeling connected with others and the group (communion) Men focus on the individual and feelings of self-protection and self-assertion (agency) Effect size tells us the impact or importance of a variable to the overall observed effect. Meta-analysis: researchers combine the individual results of different experiments to calculate an estimate of how large an effect is across many different participants, sample, experimenters, methods, and measures. D = mm mf / s. S = avg sd of male and female scores. When males score higher than females on avg, d will be pos. When females score higher than males on avg, d will be neg. Formula for d expresses difference between avg of two groups in relation to the amount of variability in each distribution.
