In previous lessons, you learned about the proper techniques researchers use when sampling a population, and how they infer meaning out of sample data. In this lesson, you will learn more about what investigators do with the numerical data they collect. You'll see how statisticians use the average of values observed in samples to accurately determine the average in the population from which the sample was drawn. You will also learn about a theory that is central to all of statistics and which allows researchers to make approximations of population values based on a small sample of data.
