how to read Table A3 on uac site? (1 Viewer)

[Sirius Black]

For physics and chemistry last year (2004 HSC)
It says that HSC Scaled Mark
Physics 47.5-->46.4
Chemistry 47.0-->46.3
The stat above for both of phys and chem are accoring the 99th percentile column
Does that mean ppl get scaled down if u get 47.5 for phys &47.0 for chem? If so, why do ppl normally say that these two subjects hav good scalings?

thanx

No.

It doesn't mean that.

Using Physics as an example, it does mean that students who received an aligned HSC mark of 47.5/50 had a scaled mark of 46.4/50. But this doesn't mean that their mark was scaled down, because scaling is applied to raw marks, not to the aligned marks reported by the Board.

You should refer to the scaled mean and scaled standard deviation to determine whether a course was scaled positively or negatively. (A course with "average" or no scaling would have a scaled mean of 25.0 and a scaled standard deviation of 12.0.)

thank you~~

Okay, so basically aligned HSC mark and scaled are two irrelevant things right?

Regarding on the mean and S.D, does a subject hav mean >25.0 a scaled up one?

Yep. Pretty much.

By the way, are you going to be in the new harry potter book?!?!? :O

Many people look only at the scaled means of courses and decide the relative scaling of courses from that. Although this is probably the best datum, it should not be the sole one.

The scaled standard deviation is also significant. If a course has a high scaled mean but a low standard deviation, it means that you have to you have to excel with respect to that candidature to do well. Generally, it can be argued that a standard deviations have comparable difficulty between courses; thus, if a course (A) has a scaled mean of 25.0 and a scaled standard deviation of 12., and another (B) has a scaled mean of 35.0 and a scaled standard deviation of 2.0, it is just as difficult to receive a scaled mark of 37.0 in both courses.

For example, in Philosophy, a mark of 48.5 is 1 SD from the mean as in Classical Greek Extension. Therefore, it is comparably 'difficult' to receive a mark of 48.5.

In my opinion, you should see where you would stand in a course, look at the scaled mark of the nearest percentile in that course, and compare those when considering scaling.

Adieux,

pi.

Sorry to revive an old thread but I'm a little confused on what the "Mark" column means.

Is that the maximum mark given for that year for that subject or like the maximum mark attainable but not necessarily was reached? If that makes sense...

And what does it mean by raw marks are scaled? Is that 50% raw external mark + 50% raw internal mark? Because the raw internal mark still has to be moderated doesn't it?

Sorry I'm quite a bit confused...
