Chi-Square (Χ²) Table | Examples & Downloadable Table. Published on May 31, 2022 by Shaun Turney.Revised on June 21, 2023. The chi-square (Χ 2) 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.
The table below can help you find a "p-value" (the top row) when you know the Degrees of Freedom "DF" (the left column) and the "Chi-Square" value (the values in the table). See Chi-Square Test page for more details. Or just use the Chi-Square Calculator. The Table
To use the Chi-Square distribution table, you only need to know two values: The degrees of freedom for the Chi-Square test; 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 ...

How can I locate the critical chi-square value from the table? You can find the chi-square critical value based on degree of freedom (df) and the alpha level (shown as p-value on the table). For instance, if df=1 and alpha = 0.05, you can find the critical chi-square value of 3.841 (see the intersection of the two red boxes below in the figure).
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 A=0.005 0.010 0.025 0.05 0.10 0.25 0.50 0.75 0.90 0.95 0.975 0.99 0.995 ; 1 : 0.39E-4 : 0.00016 :
In the chi-square table below, I highlight these two results. The chi-square table shows that our lower critical value is 0.831 and the upper critical value is 12.833. Consequently, our results are statistically significant if the χ 2 test statistic when ≤ 0.831 or ≥ 12.833.
For a chi-square test of independence with a 3×4 contingency table (df = (3-1)×(4-1) = 6) and a significance level of α = 0.01: Find df = 6 in the leftmost column; Look for the column with α = 0.01; The critical value is 16.812; Reject H₀ if your calculated chi-square statistic is greater than 16.812
One degree of freedom and 5 percent probability is 3.84 in the chi squared table. This is your critical chi-square value. Looking up df=1 and 5% probability in the chi squared table. Tip: A small value from the chi squared table means that there isn’t much of a relationship between the two variables. A larger value indicates a greater ...

In a chi-square distribution table, degrees of freedom (df) refer to the number of independent variables available for testing a hypothesis. In the table, you will find the degrees of freedom in the first column.. There are several types of chi-square distributions. Each has its own equation for calculating the degrees of freedom.
The estimated value of χ 2 or χ 2-statistic (χ² 0) is compared with the critical value of χ² from Chi-squared distribution table to check the significance of results. For locating the χ² e (critical value of χ²) in the table quickly, users can supply the values of degrees of freedom (df) and significance level (α) directly in the ...
How to Use the Chi-Square Tables. Chi-Square tables are used to determine the critical value for the Chi-Square distribution, which is commonly used in hypothesis testing, such as goodness-of-fit tests, independence tests, and variance analysis. Follow these steps to interpret the Chi-Square tables:
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.
Chi Square Table A Chi-Square table, also known as a chi-squared distribution table, is a valuable tool in statistical analysis. It provides critical values for the chi-square distribution, which is commonly used in hypothesis testing and goodness-of-fit tests. Understanding the Chi-Square Distribution The chi-square distribution is a probability distribution that arises in various statistical ...
