If its simply a matter of purchases per Customer then its a 100% increse. i.e
for week 2 you had 2 sales per 100 Customers through the door compared to 1
in week 1 which is double.

Here's a scenario:

Week 1
Visits to store = 100
Purchases = 1
Purchase rate = 1%

Week 2
Visits to store = 200
Purchases = 4
Purchase rate = 2%

Here's the question:
What is the increase in my purchase rate?

Is it 1%? Is it 100%?

Thanks for your help!
