Investigators must use care to select a sample population that is representative of the source and target populations. Well-defined inclusion and exclusion criteria serve as guidance when screening potential candidates for eligibility for participation in a study. Sampling and non-sampling errors may influence study outcomes and generalizability of results. The purpose of this short report is to review common sampling errors made when designing a study and when reporting study outcomes.
