Let's say I have the following data:
I'd like to get a percentage based off some sort of average change of the data (in the order) to get an idea of what % the data appears to be increasing/decreasing on average.
The data above is obviously increasing from start to finish (with a few random changes). But what is the average increase in a percentage format?
My first thought was to take the difference between each consecutive number pair (ie: $2-1 = 1, 3-2 = 1, 1-3 = -2,$ etc), then taking the averages of all these difference values. This might get what I want. But I was wondering if there was some more clever formulas that might do this better.
