This is surely easy but I am somewhat confused. I have a scale 1-7 (7-point-scale) and want to transform them into 0 - 100 (percentage), so 1 = 0% and 7 = 100%.
Do I have to divide 100 by 7 or 6? I ask this because 1 means absolute missing (e.g. 0%).
with dividing by 7 I have to substract 100/7 from 1 to get 0 (1 * 100/7-100/7)
with dividing by 6 I can use the same formula for all numbers: NUMBER * 100/6-100/6.
