The Chi-square goodness of fit test is a statistical hypothesis test used to determine whether a variable is likely to come from a specified distribution or not. It is often used to evaluate whether sample data is representative of the full population.

In his paper of 1941, Seal included details of some experiments he performed in an attempt to estimate the appropriate number of degrees of freedom for the chi-square goodness-of-fit test of a summation formula graduation. These results are referred to by Tetley and by Benjamin and Haycocks ...
Non-parametric tests like the chi-square test are less powerful than parametric tests, i.e., they are less likely to reject the null hypothesis, especially when it is false. A few application areas include: The chi-square test for checking the goodness of fit is utilized...

For example, if you were rolling a fair six-sided die 60 times and wanted to test whether the frequencies of each number rolled match the expected frequencies (1/6 for each number), you could use a goodness-of-fit chi-square test. Test of Independence This test examines whether there is...
