Which of the following is an example of probability sampling?a.Convenience samplingb.Snowball samplingc.Cluster samplingd.Quota sampling

To determine which of the options is an example of probability sampling, let's analyze the provided choices:

1. Convenience sampling - This is a non-probability sampling method where samples are selected based on their easy availability and proximity to the researcher.

2. Snowball sampling - This is also a non-probability sampling technique where existing study subjects recruit future subjects from among their acquaintances.

3. Cluster sampling - This is a probability sampling method where the population is divided into clusters (usually geographically), and then entire clusters are randomly selected.

4. Quota sampling - This involves the non-random selection of a specific number of participants from different subgroups. It is a non-probability sampling method.

Final Answer

The correct answer is c. Cluster sampling.
