Two samples are considered related when each score in one sample is paired with a particular score in the other sample, such as in a matched or paired design. This is different from independent samples, where participants are randomly assigned to either sample without any specific pairing or matching. Retaining the null hypothesis of the two-sample t-test does not determine whether the samples are related or not.
