# Group by aggregations

We'll use the same function we created in the [Reading Data exercise](https://www.educative.io/courses/python-data-analysis-and-visualization/exercise-reading-auto-mpg-dataset) to read in the `pandas` data frame.

We will create an additional function `group_aggregation` which will take a data frame, a group variable, and an aggregation variable. The function will group by the group variable and calculate the mean of the aggregation variable for each group. Your function will return the grouped data frame.

Try to implement the function below. Feel free to view the solution, after giving it a few shots. Good Luck!

This exercise will test your abilitiy to do group by aggregations on a pandas data frame
