Table Chi Square Distribution. Then move to the top and find the probability. 995 99 975 95 9 1 05 025 01 1 0 00 0 00 0 00 0 00 0 02 2 71 3 84 5 02 6 63 2 0 01 0 02 0 05 0 10 0 21 4 61 5 99 7 38 9 21.
Chi square distribution table 0 c 2 the shaded area is equal to fi for 2 2 fi. The degrees of freedom for the chi square test. 0 05 on the left is 0 95 on the right.
The alpha level for the test common choices are 0 01 0 05 and 0 10 the following image shows the first 20 rows of the chi square distribution table with the degrees of freedom along the left side of the table and the alpha levels along the top of the table.
To find probability for given degrees of freedom read across the below row until you find the next smallest number. Chi square distribution table 0 c 2 the shaded area is equal to fi for 2 2 fi. The first row represents the probability values and the first column represent the degrees of freedom. To use the chi square distribution table you only need to know two values.
