Abstract
This paper reports on the method of statistical power analysis and details procedures by which the research planner may design a more efficient experimental study. Attitude research published in the Gerontologist and the journal of Gerontology was submitted to a statistical power analysis. High numerical values were found, and compared and contrasted with those of past power-analytic investigations, the majority of which found low statistical power in their respective disciplines.Keywords
