@ Anon42968- Sample population statistics is very important in keeping society functioning. The characteristics of a population help the private and public sector efficiently distribute resources. Efficient economic growth is dependent on knowing things about a population. Statistics are also important in determining how much of a finite resource is left. These are some of the broader purposes of statistics, and how they relate to society, but they are also important on a small scale. Advertising, marketing, and financial forecasting are dependent on statistical analysis. Even political representation is dependent on population statistics.
