Question

You’d like to estimate the mean size of families in your community. Explain why you’ll tend to get a smaller sample mean if you sample n families than if you sample n individuals (asking them to report their family size). (When you sample individuals, explain why you are more likely to sample a large family than a small family. To think of this, it may help to consider the case n = 1 with a population of two families, one with 10 people and one with only 2 people.)
