On the following pages you will learn about both probability and non-probability sampling methods. Probability sampling is based on the idea that anyone from the population of interest should have an approximately equal probability of being selected. In non-probability sampling, however, not everyone from the population has an equal chance of being selected as a potential participant (Evans & Rooney, 2011).
In terms of social science research methods, probability sampling is more effective for surveys, and non-probability sampling is more realistic for interviews. Keep reading to learn more about both methods!
