Chapter 7. Basic Statistics

This chapter will focus on the statistics required by any aspiring data scientist.

We will explore ways of sampling and obtaining data without being affected by bias and then use measures of statistics to quantify and visualize our data. Using the z-score and the Empirical rule, we will see how we can standardize data for the purpose of both graphing and interpretability.

In this chapter, we will look at the following topics:

• How to obtain and sample data
• The measures of center, variance, and relative standing
• Normalization of data using the z-score
• The Empirical rule
