What are the two types of sampling methods used by researchers to select a sample?
What will be an ideal response?
Answers will vary. Researchers typically select a sample, a group of people (or things) who are representative of the population they wish to study. In obtaining a sample, researchers decide whether to use probability or nonprobability sampling. A probability sample is one in which each person (or thing, like an email address) has an equal chance of being selected because the selection process is random.In a nonprobability sample, there is little or no attempt to get a representative cross section of the population. Instead, researchers use sampling criteria such as convenience or the availability of respondents or information.
