Chi Square Distribution Degrees Of Freedom. Find the cell in the table corresponding to your alpha level and degrees of freedom. For upper tail one sided tests the test statistic is compared with a value from the table of upper tail critical values.

E χ2 ν. The notation for the chi square distribution is χ χ2 df χ χ d f 2 where df degrees of freedom which depends on how chi square is being used. To find probability for given degrees of freedom read across the below row until you find the.
The degrees of freedom for the three major uses are each calculated differently.
Check out this post for how we calculated this next we can find the critical value for the test in the chi square distribution table. A test statistic with ν degrees of freedom is computed from the data. While the variance is twice the degrees of freedom viz. It turns out that the test statistic for this chi square test is 0 864.
