Chi-Square Contingency Table Calculations: 5 Different Examples with Step-by-Step English Guide Chi-Square Contingency Table Calculations: 5 Different Examples with Step-by-Step English Guide The Chi-Square Test of Independence tests the association between two categorical variables using contingency tables. In this article, we will perform step-by-step Chi-Square calculations for 5 different contingency table examples in English. For each example, we will provide observed frequencies, expected frequencies, Chi-Square statistic, degrees of freedom, p-value, and interpretation. Chi-Square Formula: \[ \chi^2 = \sum \frac{(O_i – E_i)^2}{E_i} \] Where: \(O_i\): Observed frequency. \(E_i\): Expected frequency. \(\sum\): Sum across all cells. Expected Frequency Formula: \[ E_i =
