Re: Great Idea
One of the great statistical language problems.
Does Verizon mean they've reduced their churn by 2% of the amount churned, or by 2% of the customer base? (If their normal churn [by month, quarter, or whatever] is 5%, then a 2% (of the base) reduction to 3% is significant. If, on the other hand, they've only reduced the churn by 2% of the churn (0.1% of the base) then it would be meaningless.
The underlying article quotes Verizon as saying that a 0.6% churn reduction would have paid for the service, so I suspect they are measuring as a % of the base.
