The Effects of Sex Composition on Small-Group Performance in a Business School Case Competition
通过分析34位评委对37个学生团队的评分数据，发现团队性别构成与绩效正相关，并控制了平均GPA、工作经验等因素。
We found group sex composition to be positively related to team performance (β = .27; p < .001) in a business school case competition by analyzing data from 34 practitioner judges' ratings of 37 student teams. In several multiple regression equations, we investigated the effects of sex composition, controlling for such variables as average team GPA, aggregate team work experience, team size, and team coaching received, among others. In addition, we conducted factor and other psychometric analyses of the dependent variable (e.g., coefficient alpha reliability of .92). The sex-composition findings are congruent with the small-group literature on diversity and with the assumption of sex differences in cognition and communication (i.e., evolutionary theory). As a secondary objective, we present a self-developed, generic performance-rating instrument as a useful assessment tool for case competitions.
