SUMMARY
The discussion clarifies the distinct purposes of the two-sample t-test and the chi-squared test for homogeneity. The two-sample t-test is utilized to compare the means of two samples drawn from a normal distribution, while the chi-squared test assesses the similarity of distributions between two populations. It is established that the chi-squared test can be applied in a broader range of situations compared to the t-test, particularly when dealing with categorical data.
