Overview for Runs Test

Use Runs Test to determine whether the order of the data is random. If the number of observed runs is substantially greater than or less than the number of expected runs, it is likely that the data are not in random order.

For example, a researcher uses a runs test to determine whether the answers from 30 interview participants are random. Answers that are not in random order may indicate, for example, a gradual bias in the phrasing of the questions or that the interview participants are not selected at random.
