What are contingency tests?
12/06/2022 | By: FDS
Contingency tests are statistical tests used to measure the probability of an observed relationship between two or more variables. They are used to determine whether an observation is statistically significant, i.e., whether the observation is due to chance or whether there is a specific relationship between the variables. For example, contingency tests can be used to examine the relationship between a patient's sex and the result of a laboratory test.
