The article discusses how to use chi-squared test and Fisher's Exact Test to analyze data sets. The chi-squared test compares observed data with expected data under a specific hypothesis. Fisher's Exact Test calculates the exact probability of observing certain data in a 2x2 table. The researchers demonstrate these tests using SPSS software and show how to interpret the results.
