A chi-square test is any statistical hypothesis test in which the test statistic has a chi-square distribution when the null hypothesis is true, or any in which the probability distribution of the test statistic (assuming the null hypothesis is true) can be made to approximate a chi-square distribution as closely as desired by making the sample size large enough.

• Pearson's chi-square test
• Yates' chi-square test also known as Yates' correction for continuity
• Mantel-Haenszel chi-square test
• linear-by-linear association chi-square test
• Chi-square goodness-of-fit test
