RAW Score Calculator
Raw Score Calculator - from any kind of score+
To be able to calculate raw scores, you need to know:
1) Two numbers of two scales that correspond. For example, if I know that from the raw score 23, I have obtained the result 45, then 23 will be introduced into the first slot called 'Score in the raw scale' slot, and 45 will be introduced in the 'Score that correspond to the raw score' slot.
You can also use here the maximum score of the scales. For example, if I know that the maximum possible score in the raw score scale is 10, and that the maximum possible score in the transformed scale is 100, I will introduce those two numbers on these two slots. 10 would go into the 'Score in the raw scale' slot, and 100 would go into the 'Score that correspond to the raw score' slot.
2) The number from which we want to calculate our raw score. We will introduce that score into the 'Score to transform' slot.
This is the most simple formula that you can use. This formula will only work if both of your scales start at the same point, usually at 0. And if both scales are proportional. Most of the cases that you will be working at an introductory level are like this, so this formula will work for most of the scales.
