The chi-square (Χ2) distribution table is a reference table that lists chi-square critical values. A chi-square critical value is a threshold for statistical significance for certain hypothesis tests and defines confidence intervals for certain parameters. Chi-square critical values are calculated from chi-square distributions.

The Chi-Square distribution table is a table that shows the critical values of the Chi-Square distribution. To use the Chi-Square distribution table, you only need to know two values: The degrees of freedom for the Chi-Square test.
The chi-square distribution table below shows the critical values for different probability levels (P) and degrees of freedom (DF).

Chi-Square (Χ²) Distributions | Definition & Examples. Published on May 20, 2022 by Shaun Turney. Revised on June 21, 2023. A chi-square (Χ2) distribution is a continuous probability distribution that is used in many hypothesis tests. The shape of a chi-square distribution is determined by the parameter k.
The chi-squared distribution is used in the common chi-squared tests for goodness of fit of an observed distribution to a theoretical one, the independence of two criteria of classification of qualitative data, and in finding the confidence interval for estimating the population standard deviation of a normal distribution from a sample standard ...
Chi-Square (χ2) Distribution. 0 χ 2. The numbers in the table represent the values of the χ 2 statistics. Areas of the shaded region (A) are the column indexes. You can also use the Chi-Square Distribution Applet to compute critical and p values exactly. df.
