A Meta-analytic Test of the Effects of Group Diversity on Group Outcomes

Abstract

This study carried out a meta-analysis on group diversity and group outcomes. Using data from 3,534 teams in 13 studies conducted in team-level settings, it was examined whether contextual factors at research local and team-size influenced group outcomes of group diversity. This study analyzed the relationship between group diversity and group performance through meta-analytic test. The analysis included 13 papers published between 2009 and 2014. As a result of the meta-analysis that group diversity had a positive effect on group performance (Fisher`s Z = .112, k = 32, 95% CI = 0.039 to 0.183). After that, we investigated the moderating effect of the research area and team-size. As a result, research area moderating effect was significant, but team-size was not supported. Based on the above, the findings suggest implications and future research directions.
