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).
Next, we can find the critical value for the test in the Chi-Square distribution table. The degrees of freedom is equal to (#rows-1) * (#columns-1) = (2-1) * (3-1) = 2 and the problem told us that we are to use a 0.05 alpha level. Thus, according to the Chi-Square distribution table, the critical value of the test is 5.991.

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.
Find the upper-tail and lower-tail critical values of the chi-square distribution for different degrees of freedom and significance levels. Learn how to use the table for one-sided and two-sided tests with examples and graphs.
Locate the Critical Value: In the Chi-Square table: Find the row corresponding to your degrees of freedom (df). Find the column corresponding to your chosen significance level (α). The intersection of the row and column gives the critical Chi-Square value for your test. Use this critical value to compare against your calculated Chi-Square ...

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.
Discover the Chi Distribution Table: Quick Reference Guide, an essential tool for statisticians and researchers. This comprehensive guide simplifies chi-square distribution calculations, offering critical values for hypothesis testing, goodness-of-fit analysis, and more. Easily navigate degrees of freedom and significance levels to streamline your statistical workflows and ensure accurate data ...
Like all tables of critical values, this one provides the value in which you should reject the null hypothesis if your calculated value is bigger than the critical value i the table. For chi-square, the null hypothesis is that there is no pattern of relationship, but the process of Null Hypothesis Signficance Testing is the same as we've been ...
Chi square test scores that are more extreme than the critical value are statistically significant (reject H 0). Otherwise, keep the H 0 (not significant). For chi square goodness of fit (columns only), the degrees of freedom are columns (groups) - 1. The test of independence degrees of freedom are (rows - 1) * (columns - 1).

In statistics, a chi-square table lists the critical values of a chi-square distribution for different levels of significance and degrees of freedom. The degrees of freedom are proportionate to the number of variables under analysis. On the other hand, significance levels show the confidence intervals between observed and expected parameters.
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 ...
