Introduction
There are two types of chi-square tests. Both use the chi-square statistic and distribution for different purposes: A chi-square goodness of fit test determines if sample data matches a population. In a more general sense, it tests to see whether distributions of categorical variables differ from each another.
The chi-square test of independence is used to determine if there is a significant relationship between two nominal (categorical) variables. The chi-square test of independence can be used to examine this relationship. The null hypothesis for this test is that there is no relationship between gender and empathy.
