Cluster Rct Sample Size Calculator. The simplest approach for their sample size calculation is to calculate the sample size assuming individual randomization and inflate this by a design effect to account for randomization by cluster. However the calculator was also developed to be flexible enough to allow users to specify their own cluster sizes if desired.

Calculate sample size for cluster randomised trials includes cluster cross-over and stepped wedge Resources. T-value21962times the original sample size and then recalculates the total sample size and number of clusters. Note that increasing either k t or b will result to decreasing the required sample size for an SWT.
