Tutorial 1: Power and Sample Size for the One-sample t
... In carrying out a one-sample t-test we make the assumption that the observations are randomly sampled from a well-characterized population and are independent of each other (i.e., that there is no clustering). In most cases, we can easily verify this assumption. In addition, we assume an approximate ...
