When conducting a descriptive or analytic study which requires sampling a subset of the population, it is of vital importance to consider the required sample size. Although this can be easily achieved when using simple random sampling, it becomes more complex in the case of more complex sampling strategies. The following pieces of software are available to assist with these calculations:
