Please explain in mathematical terms what's happening here!?
I'm not trained in mathematics, but I need to explain the following in such terms. Could you please assist?
Three values are ranked ordinally (1 to 3) in terms of importance.
What is already obvious is that we have a curve that is progressively flattening. Now if we extend the number of values to say 12, the progressive flattening of the curve is clearer.
So here is my question: What is the nature of this function? I think it may be something like an inverse natural log (or whatever - I don't know).
I need to explain this in words so that if we didn't have the benefit of the images, that a mathematician would immediately understand what I am referring to.
