網頁For a Chi-distribution, the degrees of freedom must be an integer, but for Nakagami the can be any real number greater than 1/2. This is the critical difference and accordingly, Nakagami-m is viewed as a generalization of Chi-distribution, similar to a gamma distribution being considered as a generalization of Chi-squared distributions. 網頁2024年4月13日 · The chi-square distribution table can help you find the critical values of a chi-square distribution. It contains a list of critical values for chi-square tests with varying degrees of freedom and significance levels. The table allows you to compare the differences between observed data against critical values to conclude your hypothesis.

Since there are three intervention groups (flyer, phone call, and control) and two outcome groups (recycle and does not recycle) there are (3 − 1) * (2 − 1) = 2 degrees of freedom. For a test of significance at α = .05 and df = 2, the Χ 2 critical value is 5.99.
