To perform achi-square test, you compare a sample’s chi-square to a critical value. To find the right critical value, you need to use thechi-square distributionwith the appropriate degrees of freedom. Thenull distributionof chi-square changes with the degrees of freedom, but in a different...
Chi-square goodness of fit starts with a single categorical variable with a total ofnlevels. We test the hypothesis that this variable matches a predetermined model. The number of degrees of freedom is one less than the number of levels. In other words, there aren- 1 degrees of freedom. On...

The chi-square test statistic is chi-squared distributed with n - 1 degrees of freedom only if the: - sample has a Student t-distribution with degrees of freedom equal to n - 1. - sample is normally distributed with variance equal to. - po...

An Example of Chi-Square Test for a Multinomial Experiment By Courtney Taylor The first item of importance is the number ofdegrees of freedom. This number tells us which of thecountably infinitelymany chi-square distributions we are to use in our problem. The way that we determine this numbe...
