Select Analysis, Probability Distributions, Chi-Square Distribution.
Enter a positive integer (such as 10) for the number of degrees of freedom.
Enter either the value of the chi-square test statistic or enter the area to its right (such as 0.025).
Click on Evaluate.
Results include the value of chi-square, the area to the right of the chi-square value, and the area to the left of the chi-square value.
(The value given for “Prob Dens” (probability density) is the height of the graph of the chi-square distribution at the given value of chi-square. This value is typically not used in the introductory statistics course.)
