A chi squared test also written as χ 2 test is a statistical hypothesis test that is valid to perform when the test statistic is chi squared distributed under the null hypothesis specifically pearson s chi squared test and variants thereof. The chi square test gives a way to help you decide if something is just random chance or not. Pearson s chi squared test is used to determine whether there is a statistically significant difference between the expected frequencies and the.
The test utilizes the chi square distribution where the null hypothesis declares no association between the two variables independence and the alternative being dependent as the example below illustrates.
