WebThe formula for chi-square is: χ^2 = ∑ (O_i – E_i)^2/E_i Here, O_i = Observed value E_i = Expected value How do you calculate chi squared? The value of the Chi-squared statistic … Pearson's chi-squared test is used to assess three types of comparison: goodness of fit, homogeneity, and independence. • A test of goodness of fit establishes whether an observed frequency distribution differs from a theoretical distribution. • A test of homogeneity compares the distribution of counts for two or more groups using the same categorical variable (e.g. choice of activity—college, military, emplo… marty nesbitt
