An Exploratory Analysis of the Prevalence of Quantitative Research Concepts in Journal Articles

The purpose of this study is to explore the prevalence of quantitative researchmethodologies in published journal articles to better understand the knowledge andskills necessary for school leaders to meet the expectations of applying research findingsto practice. It examines research articles published between 2008 and 2013 inthe American Educational Research Journal, the Educational Administration Quarterly,and the NASSP Bulletin. Empirical articles comprise 91 percent of the 449 identifiedresearch articles, with 58 percent reporting the use of quantitative methodolog.

Brief Notes: Statistical Power Analysis and Research Results

I was most pleased by the recent publication by Brewer, “On the Power of Statistical Tests in the American Educational Research Journal” 1972, and understandably delighted with his heavy reliance, in accomplishing his survey, on my power handbook ( Cohen, 1969 ). I strongly agree with his stress on the importance of power analysis. Further, his survey’s confirmation of my finding of a decade ago ( Cohen, 1962 ; 1965 ) that the neglect of power analysis results in generally low power is very useful, although not surprising. Unfortunately, however, some conceptual errors in the article may seriously mislead educational researchers, and undermine our shared goal of promulgating power analysis. Hence, this note.
