Introduction

In this lesson, we will get started with some very basic statistical analysis. A statistic of data is just a summary of that data for humans and computers. Imagine you have a medical history of 2 million people from multiple hospitals, and you want to know which disease is worst among a set of diseases. Of course, you cannot go through all the 2 million people and keep comparing by yourself. With the help of statistics and good computational power, you can do it within hours. You can visualize the body temperature box plots and see that one disease causes more fever than the others.
