Increasing Sample Representativeness

Factors that influence a sample’s representativeness include:

Sample Size

  • Larger sample sizes tend to be more representative as long as the sampling and recruitment methods are appropriate.

Sampling and Recruitment Methods

  • How the sample is recruited and selected can have a large impact on its representativeness (e.g., recruiting and selecting participants from rural versus urban areas).

Module 5b Sampling Methods and Recruitment further addresses sampling and recruitment methods.
