WebThe Chi-square test statistic is calculated as follows: χ 2 ∗ = ∑ i = 1 r c ( O i − E i) 2 E i. Under the null hypothesis and certain conditions (discussed below), the test statistic follows a Chi-square distribution with degrees of freedom equal to ( r − 1) ( c − 1), where r is the number of rows and c is the number of columns.
