The Chi-Square Test procedure is useful when you want to compare a single sample from a polychotomous variable to an expected set of values. The procedure tabulates this variable into a set of frequencies and tests this observed set against either a common expected value or a customized set of expected values. The entire range of the test variable is used by default; however, its range may be restricted to any set of contiguous values. Additionally, descriptive statistics and/or quartiles can be requested.

- If your variable has only two outcomes, you can alternatively use the Binomial Test procedure.
