Chi-Square Distribution Table 0 2 The shaded area is equal to ® for Â2 = Â2 ®.

For that reason, we'll now explore how to use a typical chi-square table to look up chi-square values and/or chi-square probabilities. Let's start with two definitions.

Table 1: Critical values (percentiles) for the chi-square distribution. For each degree of freedom in the first column, the table entries are the critical values for the upper one-sided significance …

The numbers in the table represent the values of the $ {\chi^2}$ statistics. Areas of the shaded region (A) are the column indexes. You can also use the Chi-Square Distribution to compute …
