Population in the News
This week focuses on estimating population means which is a central activity in statistics. Using smaller samples statisticians often
attempt to infer population parameters. You will learn to understand the important concepts of what a population is, how it is measured,
how measurements in statistical error occur, and what they mean for the interpretation of the results.
