Quizplus · Accepted Answer

This is a convenience sampling method as the researcher has only selected those colleagues who work in the same building as the researcher. Therefore, the sample is not selected at random or according to any specific stratification or cluster method. A systematic sampling method would involve selecting individuals at regular intervals from a list or population.
