q2 · i? · review · r1
The article reports, citing Burke et al. (2006), a meta-analysis of team leadership and behaviorally oriented team performance outcomes. The review attributes these variance figures to that meta-analysis; the article prints no standardized effect size for them.
"They found that across 19 studies, task-focused leadership behaviors accounted for about 10% of variance in perceptions of team effectiveness and that empowerment behaviors (leader actions to develop self-management and/or self-leadership skills) accounted for nearly 30% of the variance in team learning"
