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. WebFor this we will need to consult a Chi-Square Distribution Table. This is a probability table of selected values of X 2 (Table 3). Table 3: Chi-Square Distribution Table. Statisticians calculate certain possibilities of occurrence (P values) for a …
