OK, confession: my Math's not that great.
And for myself, and my teachers, I would really like a graph of the grade offset and grade multiplicator settings.
Does anyone know if there's something like this? Because I'm always stuck on trial and error.
Example: today I had a teacher request this: I have a rubric with a minimum score of 0 and a maximumscore of 24. I want the grade to be a 10 with 24 points BUT a 5.5 with 16 points.
And this is where my puzzle always starts with the grade offset and multiplicator settings. After lots of trial and error, I found out that the settings need to be this:
When set to this, 24 point score a solid 10 and 16 points score a 5.5
Now I'm sure there's a way to calculate this in advance - and I'm just to limited to understand how.
Is there a math teacher that can pre-calculate these values for me somehow with a magic formula or a graph?
