it seemed like the Chi-Square test was the right one to run here. However, I wasn’t too sure what the categorical variables would be in this case and how we could run the Chi-square test here.
Figure 4 – Chi-square test using estimated parameters Since = 1.35 < 11.07 = (or p-value = .930 > .05 =α), we again retain the null hypothesis that the data are normally distributed. Examples Workbook Click hereto download the Excel workbook with the exam...

For the goodness of fit test, we need one variable. We also need an idea, or hypothesis, about how that variable is distributed. Here are a couple of examples: We have bags of candy with five flavors in each bag. The bags should contain an equal number of pieces of each flavor. ...

You may have heard of McNemar tests as a repeated measures version of a chi-square test of independence. This is basically true, and I wanted to show you how these two tests differ and what exactly, each one is testing. First of all, although Chi-Square tests can be used for larger ...
The Chi-Square (χ2) distribution is the best method to test a population variance against a known or assumed value of the population. A Chi-Square distribution is a continuous distribution with degrees of freedom. The best part of a Chi-Square distribution is that it describes the distributio...
