WebThe value of the chi-square test statistic is 0.29 + 0.20 + 0.28 + 0.19 = 0.96. There are four possible outcomes, and we lose a degree of freedom because of finite sampling. However, it turns out that we lose two more degrees of freedom. This is because the expected values in the chi-square test were based, in part, on the observed values. WebThe formula of chi-square is symbolized as follows: The value is calculated for the degrees of freedom n-1 where n is the number of classes. (i) It is used only on the numerical data, …
