Sampling

Definition

All subsets of the given frame have an equal opportunity of being selected.

This technique arranges the population based on some pre-determined order. The sample is then selected at a determined interval from the list.

During this sampling technique, the population experiences and is organized into distinct categories or classifications. The sampling frame is then organized into categories also called strata. Sampling is clustered or grouped by geography or other defining population characteristics (such as generations).

First, a given population is selected from a random list of participants. The sample is then reduced by asking questions that would narrow down the given sample.
