Question

You want to determine the average (mean) weight of all football players of a certain age. Is a cencus practice in this situation?

Answer 1

For the given scenario, we have to determine the average weight of all football players of a certain age. In this situation, the census is not practice because there would be large number of football players of a certain age. If the population size is more, then we prefer random sampling method for determination of the population parameter. In this situation, we should use random sample of some football players of a certain age and then we can compute the average weight for these football players. We can use this estimate for the population mean weight of all football players. The complete enumeration of the weights of all football players would be expensive and time consuming, so instead of census method we can use random sampling method for finding the estimate for the population mean weight of all football players.
