Exploratory data analysis

Before diving into the nitty gritty of pipelines and preprocessing, let's do some exploratory analysis of the original, unprocessed Ames housing dataset. When you worked with this data in previous chapters, we preprocessed it for you so you could focus on the core XGBoost concepts. In this chapter, you'll do the preprocessing yourself!

A smaller version of this original, unprocessed dataset has been pre-loaded into a pandas DataFrame called df. Your task is to explore df in the Shell and pick the option that is incorrect. The larger purpose of this exercise is to understand the kinds of transformations you will need to perform in order to be able to use XGBoost.
