Survey & research glossary
Plain-language definitions for the terms you'll run into designing and analyzing surveys.
Finite population correction

Forced-choice question
A question with no neutral or "no opinion" option, requiring respondents to pick a side even if their true view is mixed.
Frequency distribution
A summary showing how many responses fall into each possible answer or category for a question.
Use terms carefully
