The Situation at the Bank
• Angela Braut works in the market research unit of the customer relations section at a major bank. The market research group have recently gotten excited about a customer loyalty measure called the new Promoter Score (NPS). They have surveyed over 1000 existing customers and now want to summarize the data.
• It looks like customers do not have a high opinion of the bank at all.
• Angela needs to summarize the data in a simple way that
the senior managers will understand. She also wants to
describe any differences between age-groups and genders.
