5-Cluster sampling is when the population is divided into sections, then a section is chosen, and every individual of that section is used. An example would be to use classrooms A, B, C, and D, then choose one of those classrooms as your sample in the study.

Convenience sampling is used to get results by the easiest of ways. An example is when the researcher uses subjects close at hand.

Systematic sampling is having a place to begin and then selecting (every other, for example) of that sample. For example, lining up a class of 10 th graders and picking every 3 rd person to be part of the sample.
