THE PERCEPTIONS AND USAGE OF STATISTICAL POWER IN APPLIED-PSYCHOLOGY AND MANAGEMENT RESEARCH

We first assess the current level of statistical power across articles in seven leading journals that represent a broad sample of applied ps ychology and management research. We next survey the authors of these articles to examine their perceptions and usage of statistical power a nalysis. Finally, we examine the perceptions and usage of power analys is in a survey of authors of regression-based research appearing in le ading journals. Findings from the assessment of power and surveys of r esearchers indicate that power analyses are not typically conducted, r esearchers perceive little need for statistical power, and power in pu blished research is low. We conclude by discussing implications of low power for the field and recommending avenues for improving researcher s' awareness and usage of statistical power.
