spent an hour and a half learning how to use sigma notation so i could do this by hand, because i didn't know you could just do it like this in desmos... thanks for this, it was actually really helpful XD

I used this to compare a data point list and a function, and it seems to work. If we take the square of the output, does it give us the coefficient of determination?
