Same-Sex Homophily by Gender and Sexual Orientation (Hypothesis 2).

*** p ** p Differences in mean number of same-gender versus cross-gender friends are displayed in the form of Cohen’s d. Since these comparisons all involved within-subjects comparisons, effect size d was calculated using Morris and DeShon’s equation 8 [43] rather than Cohen’s formula [34]. Statistical significance is based on the results of paired-samples t-tests. A positive effect size indicates that participants reported having more same-gender than cross-gender friends in that group. For example, heterosexual men ages 18–29 reported having more same-gender than cross-gender friends (d = .57).Same-Sex Homophily by Gender and Sexual Orientation (Hypothesis 2).
