The Chi-Square test, also known as the χ2 test, is a statistical method used to test the independence of two categorical variables. It is used to determine whether there is a significant association between the variables or if the observed frequencies are due to chance. The test is based on the chi-square distribution, which is a theoretical distribution that describes the probability of observing a certain number of events in a fixed interval. chi square graphpad verified
