    Exploratory data analysis

    Now that you’ve learned how to ingest and inspect your data, you will next learn how to explore it visually and quantitatively. This process, known as exploratory data analysis (EDA), is a crucial component of any data science project. pandas has powerful methods that help with statistical and visual EDA. In this chapter, you will learn how and when to apply these techniques.

    Time series in pandas

    In this chapter, you will learn how to manipulate and visualize time series data using pandas. You will become familiar with concepts such as upsampling, downsampling, and interpolation. You will practice using method chaining to efficiently filter your data and perform time series analyses. From stock prices to flight timings, time series data can be found in a wide variety of domains, and being able to effectively work with it is an invaluable skill.
