Abstract: To calculate the sample size for a research study, it is important to take into account several aspects of the study design. In particular, one needs to take into account the hypotheses being tested, the study design, the sampling design, and the method to be used for the analysis. In this paper, we propose a simple method to calculate sample size for clustered continuous data under various scenarios of study design.
