Step 1: Defining Non-Random Sampling.
Non-random sampling is a technique where the selection process does not afford every population member an equal opportunity for inclusion.
Step 2: Evaluating Sampling Methods.
- (A) Convenience sampling: A non-random method of selecting participants based on accessibility.
- (B) Cluster sampling: A random method involving population division into clusters, with subsequent random selection of a subset of these clusters.
- (C) Quota sampling: A non-random method where researchers select participants to fulfill predetermined quotas.
- (D) Snowball sampling: A non-random method where current participants refer new participants.
Step 3: Determining the Correct Answer.
As cluster sampling is a random sampling method, option (B) is the correct choice.
