WebMar 29, 2013 · Alternative to Pearson's chi-square goodness of fit test, when expected counts < 5. In a part of my research, I am fitting probability distribution models for the count data (and binomial data) using Poisson, Binomial, Negative Binomial and Beta Binomial models. I have few data sets in which the observed frequency and hence the expected … WebThe results of a goodness-of-fit chi-square are χ2 (3, N = 200) = 2.92, p > .05. The results indicate that: A. There are significant effects between the number of categories and observed frequencies. B. The observed frequencies are significantly different than the expected frequencies. C.
