U3L8 - Processing Data in a System

Does anyone have a more detailed answer key than the one provided? It only has information on Scenario A. I would like to know more details about Scenarios B-H so that I can better guide students as I circulate while they work with the library data set.

I would also like detailed instructions on how to properly use filter and aggregation.

I can flag this request for the Curriculum Team!
