Chi Square Test Critical Value Table. To look up an area on the left subtract it from one and then look it up ie. The critical values are calculated from the probability α in column and the degrees of freedom in row of the table.
Df 0 995 0 975 0 20 0 10 0 05 0 025 0 02 0 01 0 005 0 002 0 001. 0 05 on the left is 0 95 on the right. For upper tail one sided tests the test statistic is compared with a value from the table of upper tail critical values.
This table this table contains the critical values of the chi square distribution.
This table this table contains the critical values of the chi square distribution. Critical values are important in both hypothesis tests and confidence intervals. For confidence intervals a critical value is one of the ingredients that goes into the calculation of a margin of error. While you may be thinking that the test is already complete and that you can withdraw a conclusion from ere the reality is that you re still a halfway.
