WebMay 31, 2024 · The chi-square (Χ2) distribution table is a reference table that lists chi-square critical values. A chi-square critical value is a threshold for statistical significance for certain hypothesis tests and defines confidence intervals for certain parameters. Chi-square critical values are calculated from chi-square distributions. WebSolution: Now calculate Chi Square using the following formula: χ 2 = ∑ (O − E) 2 / E. Calculate this formula for each cell, one at a time. For example, cell #1 (Male/Full Stop): Observed number is: 6. Expected number is: 6.24. Therefore, (6 – 6.24) 2 /6.24 = 0.0092.
