## Overview and learning goals

As we embark on this topic, ask yourself: Do I understand the following concepts and disciplines and how they fit together?

- Populations and samples
- Types of data and scales of measurement
- The discipline of probability
- The discipline of inferential statistics
- The discipline of descriptive statistics, and the different kinds of descriptive measures
- The discipline of estimation

The main learning goal of this topic is to help you do this, and will set the stage for much of the rest of the work we’ll be doing.
