Statement of study score query

[shaiga95]

For psych I got from SoS
GA1 73.5/90 standardised score~ 1.41
GA2  193/200 standardised score ~1.51
GA3   85.5/90  standardised score ~1.61
I came top for sacs and the top exam mark for exam would translate to a z-coefficient / standardised score a bit  above 1.51 So has VCAA screwed up the scaling of my sacs a little bit confused at the moment
In our psych class of 7 there was a 45,44,44,42,42 and 2  <40 for such a class do those sac marks seem low

I read somewhere else on this forum that it translates as a percentile equivalent not a z score? A 200/200 sac z score only goes up as high as like 1.6 or something, and you can defs get higher than 1.6 with an exam.

Im not sure though, can someone confirm?

I'm not sure what you mean by the whole percentile equivalent thing, but yes, you can get higher than 1.6; my Further scores were 1.704835, 1.934860, and 2.000103.

I meant for psych, but thats beyond the point, the z scores are never gonna be equivalent cos to get an equivalent z score as your further exam z scores (for example), youd need sacs that are 100+/100, which is impossible

The only explanation I can think of is the fact that your class of 7 is rather small, and it could well be the case that your class was merged into a larger cohort, maybe another school, for SAC ranking purposes.
Therefore, despite the fact you were ranked #1 in your class, you may have slipped from #1 in the merged cohort.

It would pay to check this with your school.

If however, you did go in the exam with #1 SAC ranking, I must agree that you were hard done by.

I know for a fact that we weren't combined with another school besides the minimum number is 5 students per class afaik

[Planck's constant]

OK.

I am only speculating here, but maybe the statistical moderation of SAC scores for a cohort of 7 cannot produce extreme z-scores, particularly if the 7 of you produced comparable results.

It could be similar to the 'Latin' effect. Latin hardly ever produces Study Scores of 50, due to the small number of students, of comparable ability, taking the subject.

I am going to give VCAA a ring and ask them about it does anyone have experience with this sort of thing?
