WebTo conduct this test we compute a Chi-Square test statistic where we compare each cell's observed count to its respective expected count. In a summary table, we have r × c = r c cells. Let O 1, O 2, …, O r c denote the observed counts for each cell and E 1, E 2, …, E r c denote the respective expected counts for each cell. WebGiven an by contingency table, the test statistic (𝜒2) follows a chi-squared distribution with degrees of freedom equal to ( −1)( −1). In our example: 𝜒2 2 by hand, see the Appendix.)
