Hey Coders! Ready to take your pandas analysis skills to the next level? Grouping your data by a common value and then performing some kind of aggregation function on it is a common and powerful task. Almost exactly like the GROUP BY keywords in SQL, pandas groupby() method allows you to create a group object, which can be used to find things like average math score for each race/ethnicity or gender. In fact, you can even group by multiple categories at once, and pandas makes it so easy to do. In this video, we'll learn how!
