Summary
Congratulations on your excellent progress. In this chapter and through three examples, we were able to use the programming and analytics skills that we have developed throughout this book to effectively preprocess example datasets and meet the example's analytics goals.
In the next chapter, we will focus on level III data cleaning. This level of data cleaning is the toughest data cleaning level as it requires an even deeper understanding of the analytic goals of data preprocessing.
Before moving on and starting your journey regarding level III data cleaning, spend some time on the following exercises and solidify what you've learned.
