How does 1 value affect the average?
I have a list of hundreds of numbers.
I have averaged the numbers, and the average is about 100. I want to see what impact each value has on the average. To be overly simple. If I had a list of 1, 2, 3, 4, 5, 100. The average is ~19. Without the 100, the average is 3. So the 100 has a greater impact on the average than do the other values. How do I express that? |

How does 1 value affect the average?
If you take the total of those numbers (115) and express 100 as a
percentage of the total you get 87%, i.e. the number 100 is contributing 87% to the total, whereas the number 3, for example, is only 2.6%. So, the relative "worth" or weight of a number can be expressed as: =A1/SUM(A$1:A$100) formatted as a percentage and copied down. Hope this helps.
