Part 1
The Basics
The key to successfully mastering statistics is to have a solid foundation of the basics. To get a firm grasp of the more advanced topics, you need to be well grounded in the concepts presented in this part. After a quick history lesson, these chapters focus on data, the starting point for any method in statistics. You might be surprised with how much there really is to learn about data and all of its properties. We will examine the different types of data, how it is collected, how it is displayed, and how it is used to calculate things called the mean and standard deviation.
