Cluster Sampling

Explanation:
Detailed explanation-1: -The SE is minimal for the following cluster size [9], [10]:(2) n = ( 1 − ) c s and the number of clusters then can be calculated as K = B / (c + sn). So the optimal sample size per cluster decreases as the ICC goes up and increases as the cluster-to-person cost ratio c/s goes up.
Detailed explanation-2: -Step 1: Define your population. Step 2: Divide your sample into clusters. Step 3: Randomly select clusters to use as your sample. Step 4: Collect data from the sample. 07-Sept-2020
