If the test statistic is greater than the upper tail critical value or less than the lower tail critical value we reject the null hypothesis. The significance level α is demonstrated with the graph below which shows a chi square distribution with 3 degrees of freedom for a two sided test at significance level α 0 05. The chi square distribution table is a table that shows the critical values of the chi square distribution.
For two sided tests the test statistic is compared with values from both the table for the upper tail critical values and the table for the lower tail critical values.
Values of the chi squared distribution. Or just use the chi square calculator. So in order to use the chi square distribution table you will need to search for 1 degree of freedom and then read along the row until you find the chi square statistic that you got. For a chi square test of the independence of two categorical variables we have a two way contingency table with r rows and c columns.
