Because Churn within last month is a dichotomous variable, the mean tells us the proportion of churn within each customer type. Multiplying these proportions by 100 expresses the same data as percentages.

  • For example, the percentage of churn for customers subscribing only to basic service was 31%.
  • Similarly, customers who prefer more high-end electronic services churned at a rate of about 27% within the last month.
  • There are about 280 customers who subscribe to a set of convenience services (three-way calling, call forwarding, call waiting, etc.). Of these, only 16% recently churned.
  • Customers who take advantage of all of the services offered by the firm churned the most--37%, or 10% higher than the average of all customers within the last month.
