A list containing customer and customer purchase information has the
following columns: customer name, location (of the customer, i.e., North,
South, East, and West), customer income, customer age, and mode of
payment during last purchase (cash or card). A pivot table to find the
number of customers in each location and containing age, income, and
purchase information of customers needs to be created. Where must the
“location” field be dropped in the pivot table skeletal structure to create
such a table?
