Chi-square is not as complicated as some statistical tests and is sometimes done by hand. You can use the formula below, entering the observed (O) and expected (E) frequencies for each group. By summing up the calculated values for each of the categories, we can calculate the chi-square...

Pearson’s Chi-Square Test formula is - Where X^2 is the Chi-Square test symbol Σ is the summation of observations O is the observed results E is the expected results The shape of the distribution graph changes with the increase in the value of k, i.e., the degree of freedom. ...
FormulaExplanation is the chi-square test statistic is the summation operator (it means “take the sum of”) is the observed frequency is the expected frequency The larger the difference between the observations and the expectations (O − E in the equation), the bigger the chi-square will ...
