Chi-square tests are nonparametric tests that examine nominal categories as opposed to numerical values.
Consider a situation in which you may want to transform numerical scores into categories. Provide a specific
example of a situation in which categories are more informative than the actual values.
Suppose we had conducted an ANOVA, with individuals grouped by political affiliation (Republican, Democrat,
and Other), and we were interested in how satisfied they were with the current administration. Satisfaction was
measured on a scale of 1-10, so it was measured on a continuous scale. Explain what changes would be
required so that you could analyze the hypothesis using a chi-square test. For instance, rather than looking at
test scores as a range from 0 to 100, you could change the variable to low, medium, or high. What advantages
and disadvantages do you see in using this approach? Which is the better option for this hypothesis, the
parametric approach, or the nonparametric approach? Why?”
