Survey & research glossary
Plain-language definitions for the terms you'll run into designing and analyzing surveys.
Open-ended question
A question that lets respondents answer in their own words rather than picking from fixed options, such as a short-text or long-text field.
OpenID Connect
An identity protocol built on OAuth 2.0 used for single sign-on, letting a user authenticate through their organization's existing identity provider.
Outlier
A response or value that differs sharply from the rest of the data, which can distort averages if not identified and handled deliberately.
Clear definitions improve survey decisions
Terms such as anonymous, representative, significant, confidential, compliant, and secure carry specific expectations. Use them only when your survey method and implementation actually support the claim.
