Hi there,

I am currently working on some data for a project before recently encountering a problem.

Now the bolded area in the table is class, as the class increases so should the quality of the number.

I'm faced with a negative 15, 11 & 6 in my sample which I need to turn into a positive figure.

What I'm after is having the highest possible class with the lowest number for project reasons so it would be a negative distribution.

Could it be possible to add the numbers together so with 15 being the lowest despite representing the highest class.
