I haven't been on here for a very long time so it's nice to come back. I have a problem. I'm making a scoring system based on multiple input parameters that's probably overcomplicated but it works like this: Low score if most parameters are low. High score if most parameters are high. Low medium score if more parameters are low than they are high. High medium score if more parameters are high than they are low. High score if few parameters are extremely high. Low score if few parameters are extremely low. If parameters are all similar then score is an average of them. Each parameter is a score from 0 to 1 with any number of decimal places. There are 4 parameters for one variant and 3 for the other. Does anybody have any ideas? It's difficult to explain it in detail and I'm honestly not sure if it's possible. Thanks for any help.

When is a score low, high, extremely low and extremely high? For example, is a low score anything below 0.25?

There's unlikely to be a single equation, but you can define a piecewise function. I can't do that here because I don't know what range of scores you are using, but it isn't too difficult.

All the scores are decimals between 0 and 1.
