A related samples t test (or paired samples t test) is typically used when comparing the means of two related or dependent samples, such as before and after measurements on the same individuals. This test has higher power to detect differences between the means and is more likely to result in a decision to reject the null hypothesis compared to a two-independent sample t test, which compares the means of two independent samples. In this case, the related samples t test takes into account the correlation between the paired data points and can result in a more precise estimate of the mean difference.
