Introduction

Math seems to be a scary thing for many people. If you tend to get scared by thinking about numbers and what to do with them, this module is for you. We will tame the beast and show you how much you can do – with counting, adding, and dividing numbers.

Common problems we address

When working with data, we run into a few common problems we will address with the methods we learn here:

• What is “normal”?
• What is different / special?
• How do I compare two different entities (e.g. countries)?.

What am I dealing with?

When working with multiple values in data, one of the key points of information you can get is how the data is distributed. This helps you figure out what you are dealing with.
