When we mention filtering a pandas table, also mention, that the criteria should be independent of the thing that you are filtering.

Wrong:

pd['area, pd['area'] > 5].mean()

likely wrong:

pd['area, pd['diameter'] > 5].mean()

likely right:

pd['area, pd['intensity'] > 5].mean()

Later, refer to this when discussing correlation analysis with pearsons coefficient

Good idea, let's integrate such examples for the next course! :)
