Would have to be specific as people registered in the fan club . If you see every senator fan across the world, harder to qualify: citizens of canada. For multiple reasons, it is not typically possible to test entire populations. The set of individuals of interest to a researcher. A set of entities concerning which statistical inferences are to be drawn. Sampling: the variety of ways of selecting individuals to participate in a research study.
