There are different chi-square distributions depending on the degrees of freedom associated with them.

Question

Quizplus · Accepted Answer

The chi-square distribution is a family of probability distributions that are dependent on the degrees of freedom (df) associated with the sample. The degrees of freedom allow for the variance of the sample statistic to vary, and so the shape of the distribution changes as the degrees of freedom increase or decrease. Therefore, there are different chi-square distributions depending on the degrees of freedom associated with them.
