After introducing all of the three languages in the previous three chapters, it is time to do some serious work. Before doing some advanced analysis, you need to understand your data. In this stage, you typically do some preliminary statistical analysis and quite a few data visualizations.
In this chapter, you will learn the following topics:
- A life cycle of a data science project
- Ways to measure data values
- Analyzing continuous variables with descriptive statistics and visualizations
- Analyzing discrete variables with frequency tables and graphs
- Getting a basic idea about the associations between pairs of variables
