Abstract des Autors

This study was designed to investigate the power of the research studies published in the Research Quarterly. A survey of major articles dating from October 1969 to May 1971 was made in regard to statistical tests used, levels of significance, the sample size, and power. It was noted that statistical inferential testing was conducted in 136 of the 151 articles, with the t and ANOVA tests being the most commonly used. Cohen's (3) tables and metric free values for effect size were used to estimate the power of the 82 t and 179 F tests which were reported in 106 of the studies. An analysis of the results showed that the researchers would have made a valid rejection of Ho on the average approximately 78 % of the time when using a large effect size, 50 % of the time when using a medium effect size, and 13 % when using a small effect size. Some suggestions were presented to assist in increasing the power of statistical tests used. Verf.-Referat
