# X^{2} distribution

The table below shows critical values for the chi-squared (χ

^{2}) probability distribution. The table displays χ^{2}values corresponding to selected alpha values from 0.995 to 0.001. These values are used for determining significance when doing chi-squared goodness-of-fit tests and chi-squared tests of independence or homogeneity. Typically, if you are deciding whether the numbers of obsverved values in the categories deviate significantly from the model expectation or predictions based on independence of homogenity, you are interested in whether the calculated χ^{2}value exceeds the χ^{2}value in the table below corresponding to the column for α=0.05.
