Chi Square Test Statistic Example. This chapter presents material on three more hypothesis tests. The chi square goodness of fit test can also be used with a dichotomous outcome and the results are mathematically equivalent.
Here are a few examples. If you know the value of one variable it does not help you. As such we have to divide the significance level by two and screen our test statistic against the lower and upper 2 5 points of χ2 23 χ 23 2.
For brown we have 42 100 2 100 33 64.
An example research question that could be answered using a chi square analysis would be. Our chi squared statistic was six. There are no relationships between the categorical variables. We presented a test using a test statistic z to test whether an observed sample proportion differed significantly from a historical or external comparator.
