Pearson’s chi-square (Χ2) tests, often referred to simply as chi-square tests, are among the most common nonparametric tests. Nonparametric tests are used for data that don’t follow the assumptions of parametric tests, especially the assumption of a normal distribution. If you want to test a hypothesis about the … See more Both of Pearson’s chi-square tests use the same formula to calculate the test statistic, chi-square (Χ2): Where: 1.
