PRIMARY AND SECONDARY DATA: WITH A DISCUSSION ON SAMPLING
Probability and nonprobability samples
Probability samples are respondents identified through the use of probability sampling techniques. Probability sampling is a technique in which the members of the research population have a known chance to be picked as respondents in a particular study. Nonprobability sampling is a technique in which the chance that members of the target population to be picked as respondents is unknown.
A common example of probability sampling techniques is simple random sampling. In this technique, the chance that a member of the population will be picked is known and equal. In a population of 5,000 members, the chance that a member is chosen as a sample is 1/5000. Other probability sampling techniques are: systematic sampling, cluster sampling, and stratified sampling.
