Exercise Details:
Member Referrals The CEO has come to your desk and explained that we want to increase signups from our referral scheme . As part of this effort, we are keen to understand at what point in the member lifecycle members refer other people. There are 2 CSV files attached to your email that contain information on our customers and their referral behaviour:
● The Customer Info CSV contains information on customers and metadata for each customer. It is a representative sample of the whole customer database
● The Referral Info CSV is a log of sign-ups we have received from the referral channel Use this information to answer the questions below:
- When do members refer? (Try to think about each member lifetime, starting from when they sign-up to Bulb. The number of Bulb members is growing very quickly. A lot of Bulb members have not been with Bulb for very long. Think about how this might affect your conclusions.)
- Does the channel members are acquired from significantly impact how they refer? Do you think we need a larger sample size to be sure?
- We can send an email to members to invite them to refer their friends. We can choose when, and to whom, we send the emails. How would you suggest we proceed?
