  • Probability (random) sampling is always encouraged to obtain accurate information about the population.
  • However, it is not always appropriate to implement the most rigorous sampling techniques. This may be due to...
    • Resource constraints (funding, time, etc.)
  • Non-probability sampling methods can be used in descriptive, exploratory, and qualitative studies
  • Sometimes, if feasible, organizations choose to include everyone in their evaluations to inform internal practices and policies
