• You need to remember that, by definition, Statistics is a study in which data is collected, analyzed, and then this is used to make a conclusion.

In this case, you can identify that the Statistic is the income obtained from the sample selected.

• By definition, the Population is the set of all the values or the set of all the individuals selected (the entire group).

In this case, as the U.S. Census Bureau needs to estimate the median income of males in the U.S, the population is the set of incomes of all males in the U.S.

• By definition, the Sample is a part of the Population.
