Chi Square Distribution Table for Degrees of Freedom 1-100

How to use chi squared table?

The first row represents the probability values and the first column represent the degrees of freedom. To find probability, for given degrees of freedom, read across the below row until you find the next smallest number. Then move to the top and find the probability.

For example, if your df is 7 and chi-square is 21.01, then your probability will be written as P<0.005.
