Sample Size Estimation in Cluster Randomized Educational Trials: An Empirical Bayes Approach
Rotondi, Michael A.; Donner, Allan
Journal of Educational and Behavioral Statistics, v34 n2 p229-237 2009
The educational field has now accumulated an extensive literature reporting on values of the intraclass correlation coefficient, a parameter essential to determining the required size of a planned cluster randomized trial. We propose here a simple simulation-based approach including all relevant information that can facilitate this task. An example and corresponding computer code is attached. (Contains 3 tables and 1 figure.)
