Degree Freedom Chi Square Distribution Chart. The chi square distribution is a special case of the gamma distribution and is one of the most widely used probability distributions in inferential statistics notably. 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.
Values of the chi squared distribution. At this point you will need to know how many degrees of freedom you have. 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 is a special case of the gamma distribution and is one of the most widely used probability distributions in inferential statistics notably.
Or just use the chi square calculator. Thus according to the chi square distribution table the critical value of the test is 5 991. Chi squared distribution table. Values of the chi squared distribution.
