Correction for Guessing #71

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi All,

I'm Bob from the Netherlands and I'm studying medicine. Our test are not 
standard multiple choice questions but have correction for guessing with the 
possibility to fill in a question mark.

This means that when you have a 2 answer question like:
What color is the sky?
A blue
B green
? I don't know

If you fill in this with A, you get 1 point.
If you fill in this with B, you get -1 point
If you fill in ?, you don't get point (minus or plus)

This is to test knowledge and discourage gambling.

So for a 3 answer question look like:
What color is the sky?
A blue
B green
C orange
? I don't know

If you fill in this with A, you get 1 point.
If you fill in this with B, you get -1/2 point (1 point earnable, 2 wrong 
answers)
If you fill in this with C, you get -1/2 point (1 point earnable, 2 wrong 
answers)
If you fill in ?, you don't get point (minus or plus)

Exact the same for a 4 answer question, if wrong -1/3 point
5 answer question (maximum), if wrong -1/4

I was wondering if this type of scoring already exists in Flubaroo, and if not: 
is it possible to make this?

Greetings,
Bob Emmen

If you reverse your answers and always have answer "A" always be the ?/I don't 
know, you could use the function countif on A's and add that to your total, 
then dividing that by 2 points per question.
