Response rate = responses ÷ invitations × 100= 22.8

How is response rate calculated exactly?+
It's the number of completed responses divided by the total number of people invited to participate, expressed as a percentage. If 150 out of 500 invited people respond, the response rate is 30%.
What counts as a valid response for this calculation?+
Conventions vary: some researchers count only fully completed surveys, while others include partial responses above a certain completion threshold. Decide and state your definition clearly, since it directly changes the reported rate.
Why does response rate matter for research validity?+
A low response rate raises the risk of non-response bias, meaning the people who did respond may differ systematically from those who didn't, which can skew results even if the raw sample size looks adequate.
What's considered a 'good' survey response rate?+
It varies enormously by method and context: mail surveys often see 20-30%, online surveys can be much lower (single digits to 20%), while well-incentivized or highly engaged panels can exceed 50%. Compare your rate to similar studies in your field rather than a fixed universal benchmark.
Can I improve response rate calculations by excluding bounced invitations?+
Yes, a more accurate rate excludes invitations that never reached a valid recipient (bounced emails, wrong addresses) from the denominator, since those people never had a real opportunity to respond. This is sometimes called the 'adjusted' response rate.
