"Using Power Tables to Compute Statistical Power in Multilevel Experimental Designs"

Spyros Konstantopoulos

Practical Assessment, Research & Evaluation Vol. 14, No. 10 (May 2009)

Power computations for one-level experimental designs that assume simple random samples are greatly facilitated by power tables such as those presented in Cohen's book about statistical power analysis. However, in education and the social sciences...

Beth W. Kubitskey; Richard J. Vath; Heather J. Johnson; Barry J. Fishman; Spyros Konstantopoulos; Gina J. Park

Teaching and Teacher Education: An International Journal of Research and Studies Vol. 28, No. 3 (April 2012) pp. 418–427

As teacher professional development research includes more experimental designs, new challenges arise. We examine the threat of participant attrition as an example of the types of problems researchers face. Counter-intuitively, higher levels of...
