Summary

Instruction

Great! Now, let's combine a few techniques (filtering, grouping, and averaging) to find another interesting metric.

Exercise

Show the name of each neighborhood alongside the average overall_satisfaction. Sort the neighborhoods by the average in descending order. Only consider offers with more than 10 reviews.

Stuck? Here's a hint!

Use the functions in the following sequence:

  1. Filter for reviews > 10.
  2. Group by neighborhood.
  3. Calculate average for overall_satisfaction.
  4. Sort the values.

You can do all of that in a single line of code.
