In what situations should paired sample t-tests be used?

Paired sample t-tests should be used in situations where the same group of individuals or objects is measured or observed under two different conditions or time points. These tests are particularly useful when the data sets are paired or matched, meaning there is a natural connection or correspondence between the two sets of measurements. The paired sample t-test is commonly utilized in various fields, such as medicine, psychology, and education, to compare the means of related variables before and after an intervention or treatment. By comparing the differences within pairs, this statistical test allows researchers to determine whether any observed changes are statistically significant.
