Potential problems in the statistical control of variables in organizational research: A qualitative analysis with recommendations

The author examines statistical control in a random sample of 60 articles pub-lished in four top journals during 2000 to 2002. Authors’bases for including con-trol variables, clarity regarding measures and methods, and reporting of results were recorded. Potential problems included a lack of explanations for inclusion, unclear descriptions of measures and methods, incomplete reporting, and other flaws. Implications for interpreting results, replication, future reviews, and effect sizes are discussed. Twelve recommendations for addressing these issues are offered
