# Looking at Data

Looking at Data

### This topic teaches students about different types of data sets and different ways of representing data. Students learn how to familiarize themselves with new, complicated data sets. This topic will usually include some instruction in the use of various software programs to interpret, analyze and present data. Students learn how to use graphics and figures to represent data and convey complicated, important information in an interesting, memorable way.

Topic Learning Outcome: Upon mastering this topic, students will have experience with the process of familiarizing themselves with and learning to understand new and increasingly complicated data sets. Students will be familiar with at least one statistical software program, and will understand how tables, charts and graphs can be used to present complicated information in a digestible way.
