Chi-Square (Χ²) Table Examples & Downloadable Table

WebTo calculate the degrees of freedom (df) for a Chi-Squared Test can be done as follows; For a two-way table df = (m - 1) (n - 1) // where m = # of columns & n = # of rows For a one way table df = k - 1 // where k equals the number of groups So in short, yes; in a one way table that deals with 2 groups will correspond to 1 degree (s) of freedom. WebSo our critical chi-square value is 4.60. So another way to visualize this. If we look at the chi-square distribution with 2 degrees of freedom, that's this blue one over here, at a value of-- I'm trying to pick a nice blue to use-- at a critical value of 4.60. So 4.60-- this is 5-- so 4.60 will be right around here.
