I have 5 values, for example like this:
3
11
8
5
8
I want to calculate the average difference between them.
If I had just two values, say 3 and 11, the difference would be 8.
But how do I do this when I have more values (for example five as in my example above)?
I can not show the answer in detail because I can not format math in this board. Please refer to the mathematics subboard for math related question.
Not exactly sure what you are after but it might be the standard deviation
The standard deviation is a measure of the relative deviation from each number with respect to the ensemble average.
