WebOne-Way Chi-Square. Chi-Square "Goodness of Fit" Test. The logic and computational details of chi-square tests. are described in Chapter 8 of Concepts and Applications. This unit will calculate the value of chi-square for a one-dimensional "goodness of fit" test, for up to 8 mutually exclusive categories labeled A through H. WebApr 23, 2024 · There are three categories (the three genotypes) and one parameter estimated from the data (the Mpi90 allele proportion), so there is one degree of freedom. The result is chi-square= 1.08, 1d. f., P = 0.299, which is not significant. You cannot reject the null hypothesis that the data fit the expected Hardy-Weinberg proportions.
