The primary issue in choosing a sample size when performing cluster sampling is selecting the number of clusters. This is because the cluster size and number of clusters can both impact the precision and representativeness of the sample. If the sample is too small, there may not be enough clusters to accurately represent the population. However, if the sample is too large, it can increase costs and may not provide any additional benefits in terms of precision or representativeness. Therefore, selecting an appropriate number of clusters is essential for effective cluster sampling.
