Determining Sample Size

Determining how many responses you really need can be tricky. These resources can help you figure out what is right for your assessment.

Sample Size Calculators

Things to Consider

  • Are you looking at the entire population, or just a sample?
  • Would looking at a cohort make more sense for your study? 
    • A cohort is a single group followed from one fixed point in time to another fixed point in time. Example: Looking at a group of students when they are freshmen, then looking at them again when they are seniors.
