Abstract

There is a real and impactful pitfall in simple random sampling when the sampling unit is related but not identical to the proper unit for the parameter of concern. The project leader’s awareness of the pitfall and the coach’s understanding of it are essential. Detecting the problem allows them to make the best decision for that project.
