Welcome to Unit 9: Statistics and Probability. Statistics is a broad field that allows us to collect, analyze, and interpret all kinds of data. It's used by people in all professions and all walks of life, even if they may never realize they're using it.

Probability is a related field that helps us figure out how likely something is to happen. We use that in everyday life as well.

The measures of central tendency include several different tools that help us analyze and interpret data.

You'll need to know how to use these tools not just on the math test, but on the social studies and science tests as well.

In this lesson, we'll learn about mean, median, mode, and range.
