Summarizing dataWe often want to take a big collection of
individual records and pile them into categories
Trick: Visualize the piece of paper that would give you the answer you seek
Tool: Pivot tables

Pivot table exampleData: Region, town name, crimes, etc.Question: “How many crimes occurred in
each region?”Visualize the piece of paper that would
answer the question
