So, in this chapter, you started with some real work. You were given a brief introduction into statistical measures that describe the distribution of a variable, and how to calculate them in three different languages. This visualization of statistics and data can sometimes already be the final result, and everything you need for a final report. However, in a data science project, this is just an initial step.
In a real-life project, you spend about 70% of the time with data overview and data preparation. This means that there is some more tedious work waiting for you in the next chapter, where I will deal more with the data preparation tasks.
