Detailed explanation-1: -Non-probability sampling is a method of selecting units from a population using a subjective (i.e. non-random) method. Since non-probability sampling does not require a complete survey frame, it is a fast, easy and inexpensive way of obtaining data.
Detailed explanation-2: -Cluster sampling It is a probability sampling method, not a non-probability sampling method. In cluster sampling, the population is divided into smaller groups called clusters, and a random sample of these clusters is selected.
Detailed explanation-3: -Probability sampling involves random selection, allowing you to make strong statistical inferences about the whole group. Non-probability sampling involves non-random selection based on convenience or other criteria, allowing you to easily collect data.
