A related sample refers to a set of data points that are linked or paired in some way, often involving the same subjects measured under different conditions or at different times. This is commonly used in statistical analyses, such as paired t-tests, where researchers compare the outcomes of two related groups. Examples include pre-test and post-test scores for the same group or measurements taken from matched subjects. The relationship between the samples helps control for individual variability, enhancing the reliability of the results.
