The study compared the Chi-Square test and Fisher's Exact Test for analyzing small sample data in 2 x 2 tables. They found that the Chi-Square test can give inconsistent results, especially with small sample sizes. In some cases, the two tests disagreed on the conclusion about the Null Hypothesis. Fisher's Exact Test is recommended for more accurate results in these situations.
