Easy Question On Multiple Choice.... Confused

[ISITIEIW]

Hey, i was doing a multiple choice question and i got 0.83/1 on it... There were 6 options to choose from and you could choose as many as you liked. I only picked one of the options. I'm confused as to how or what equation is used to calculate what mark you will get on each multiple choice question.

On the same quiz, i got 0.67/1 on a different question when there were 6 options to choose from and i picked all of them.

What equation is being used to calculate my mark??

Thanks

It's impossible to really know, but there are popular methods for grading multiple choice questions. Usually they are some variant of: give 1 point for every correct choice, remove 1 point (or half a point) for every incorrect choice, where choosing too many options for a given question counts as an incorrect choice, give no points (or remove a quarter point) for not answering a question at all. But it may also be something completely different.

Furthermore, after the grade is calculated your grade may be arbitrarily raised or lowered by the teacher after being compared with the class' grade distribution, this is called grading on a curve and is done to help student's grades reflect their position relative to their classmates (more info here: Grading on a curve - Wikipedia, the free encyclopedia). Note this isn't always the case, depending on your country, year, course and teacher. It may even depend on the exact assignment or time of year. But generally if no marking schedule (note that tells you how you will be marked) is released then it's a good bet grading on a curve is going to be used.

So basically, if you really want to know exactly you should ask your teacher for how the grades were calculated, because only he/she knows for sure, and I'm sure he/she would be happy to explain if time permits.​
