TO ALL POSTERS IN THIS THREAD: It IS STUPID TO RELY on that TABLE A3 to determine how well each subject scales...... That table only
shows the DISTRIBUTION of scaled marks for the cohort of each subject, NOT how well each subject scales.
I quote: page 7 of
http://www.uac.edu.au/documents/atar/2010-ScalingReport.pdf
3.2.3 Combined courses
As the Board places English Standard and English Advanced raw marks on a common scale, these courses
are combined and scaled as a single course, but are reported as separate courses in order to be
consistent with the Board’s reporting practice.
The above passage says that advanced and standard english have the same scaling.....yet I see 32.5 as the mean scaled mark for advanced english and 17.3 for standard english on table A3, page 35 of the scaling report.
The figures on table A3 only indicate the DISTRIBUTION of scaled marks. THEY DO NOT INDICATE HOW WELL EACH SUBJECT SCALES.
So Chemistry DOES NOT NECESSARILY scale better than physics, even if chemistry (31.7) has a higher SCALED MEAN than physics (30.5). The numbers in the brackets are the scaled means.
And DAMN it took me a long time to realise this.
