Grade distrubution vs study score
Galvanic Cell:
Hello,
I have been reading the revolutions grade distrubutions from 2009,
( http://www.vcaa.vic.edu.au/vcaa/vce/statistics/2009/section3/vce_history_revolutions_ga09.pdf )
i dont really know how to read this...but from what i gather...it is indicating a C+ for the exam correlates to a study score of 30?
is this correct, or am i reading it wrong?...
_avO:
The median indicates an SS of 30
So if the median is a B+, then 50% of people get less then a Mid B+ (roughly) and 50% of people get higher then a Mid B+
In exams the median will be a C+ because they make the distribution so that the median is exactly C+ (this is where they determine how many marks the average was [and hence why the cutoff for an A+ is always changing] and thus that is the median, i.e. C+)
From the information provided, you will need a B+ B+ C+ for a rough SS of 30
Hope this helps. :)

So a C+ isnt a representation of the mark u got on your exam? Its more of a percentile ranking?
lol confusing. :s
_avO:
Yes it does represent the mark you got, but firstly the VCAA must determine everyone's marks and put it on this distribution, and thus allocates a letter grade to each range of marks
For example a C+ for Accounting requires 89-110 out of 180 which is 49%-61% on the exam but
a C+ for Chemistry requires 84-98 out of 150 which is 56%-65% on the exam.
This is due to the level of difficulty in Accounting which overall, students found harder then that of Chemistry and hence they got a median less than Chemistry, however they still get a C+ because it is the middle 50% of the state

Are those grades you used from the midyear exams?
