Tests for Several Related Samples

The Tests for Several Related Samples procedure compares the distributions of two or more variables.

Example. Does the public associate different amounts of prestige with a doctor, a lawyer, a police officer, and a teacher? Ten people are asked to rank these four occupations in order of prestige. Friedman's test indicates that the public does associate different amounts of prestige with these four professions.

Statistics. Mean, standard deviation, minimum, maximum, number of nonmissing cases, and quartiles. Tests: Friedman, Kendall's W, and Cochran's Q.

Tests for Several Related Samples Data Considerations

Data. Use numeric variables that can be ordered.

Assumptions. Nonparametric tests do not require assumptions about the shape of the underlying distribution. Use dependent, random samples.
