Hierarchical multiple regressions controlling for task performance and movement
Hierarchical multiple regressions controlling for pubertal stage, task performance, and movement
Hierarchical multiple regressions controlling for age
Linear regressions (not controlling for age because lack of age correlation with estradiol)
Hierarchical multiple regressions controlling for age
Cohen’s f2 for hierarchical multiple regressions; small, medium, and large effects: 0.02, 0.15, 0.35 (Cohen, 1988).
