- The chi-square test for independence is similar to a correlation in that it evaluates the relationship between two variables. True or false. Explain your answer.
Homework Answers
This statement is True. Like the correlation, the chi square test of independence also evaluates the relationship between two variables. However, the difference is that in chi square testing, only categorical variables are used. This means that the variables are measured in the nominal scale.

Suppose that you wish to perform a chi-square test of independence. The two variables under consideration are sex and blood type. True or false, if the two variables are not associated, we would expect that in the sample, the number of women with a given blood type would be roughly equal to the number of men with the same blood type? If the statement is false, rewrite it so that it is true.
