This procedure performs item analysis. Item analysis studies the internal reliability of a particular instrument (test, survey, questionnaire, etc.). This instrument usually consists of several questions (items) which are answered by a group of respondents. Issues that arise include whether the instrument measures what was intended (does a particular IQ test reliably measure an individual’s intelligence?), whether it produces the same results when it is administered repeatedly, whether it contains cultural biases, and so on.
