Raw Score Scaling Help!

[ShotoJuku]

[COLOR="Navy"]The safest "raw answer" to your question is to have answered slightly better than half of the total number of questions correctly. There is no exact science and no true formula, however answering MORE than half correctly will usually give you a pass.

I cut and pasted this formula so you can see the basic idea. I do not recall who came up with this but it is a good conceptual blueprint.

FACT: The lowest possible score is a 20. The hight possible is an 80.

FACT: Approx. 1/2 the questions on the test must be successfully answered to get a 50, or a pass.


Now, the hypothesis: In a 100 question test, such as Sociology and many others, there are only 60 possible points (between 20-80) for 100 questions.

60 points divided by 100 questions = .6pts

If each questions is worth .6 points, 50 correct questions = 50q X .6pts = 30pts

You must add 20 since 0 correct questions = 20pts.

30 points + 20 points = 50 points, or a pass.

Now:

If each point in a 100 question test is worth .6 points, 100 questions X .6 points = 60; 60 + 20 = 80.

By this formula, answering 75 questions correctly would translate to a score of 65.[/COLOR]
