• A sample chosen based on alphabetical order

• A subset of individuals or items chosen from a larger set in a way that every individual or item has an equal chance of being selected

What is a systematic sample?

• A type of non-probability sampling method

• Selecting the first few members of the population to be included in the sample

• Choosing the most common members of the population to be included in the sample

• A type of probability sampling method where every nth member of the population is selected to be included in the sample.

What is a cluster sample?

• A cluster sample is a sampling technique where only one cluster is selected for inclusion in the study.

• A cluster sample is a sampling technique where the population is divided into clusters and then a random sample of clusters is selected for inclusion in the study.

What is a representative sample?

• A sample that is randomly selected from a different population

• A sample that is chosen based on convenience rather than representativeness
