I'm calculating the conversion rate by employee.
Employee1 got 2 new customers out of 8 that he was working with.
Employee2 got 3 out of 6.
Employee3 got 0 out of 2.
- Conversion rate of Employee1 is 2/8 = 0.25
- Conversion rate of Employee2 is 3/6 = 0.5
- Conversion rate of Employee3 is 0/2 = 0
- Conversion rate total is 5/16 = 0.3125
I'm trying to figure out how much of the total was due to Employee1, 2 and 3?
$$0.3125\cdot {2\over 5}=0.125\\0.3125\cdot {3\over 5}=0.1875\\0.3125\cdot {0\over 5}=0\phantom{0000}$$
It really is that simple. Until you take other factors into consideration, like the comments did.
