WebIn these results, the Pearson chi-square statistic is 11.788 and the p-value = 0.019. The likelihood chi-square statistic is 11.816 and the p-value = 0.019. Therefore, at a … WebMay 2, 2024 · We can see that the difference between our χ2 value and Pearson’s χ2 value is negligible, considered against the relevant χ2 probability distribution. In practical terms, the χ2 value has to be quite small in order to accept the null hypothesis. The null hypothesis, in this case, is that the observed data arise from a binomial distribution.

A value of 0 indicates that there is no association between the two variables. A value greater than 0 indicates a positive association; that is, as the value of one variable increases, so does the value of the other variable.
