Understanding data analysis with Python
In the previous section, we introduced some of the libraries that we can use to analyze data in Python. In this section, we will be looking at one example and multiple code snippets to build a bar graph using real data and Matplotlib, but before we do so, let's review why Python is so important with regard to data analysis.
As Python is object-oriented, it allows us to streamline really complex and/or large datasets. This allows great readability of the data and using the libraries can produce data representations such as tables and visual models that allow us to predict where our data is going, create regression analyses, and much more. As mentioned in the introduction of this chapter, data analysis is also critical for decision-making. A well-designed experiment produces data that we can rely on and that is generalizable. Data analysis can be a tool for more equality and equity in our society.
All that being said, we are going to...
