English Statement of Marks - please help me understand?

[New2VCE]

Can anyone please explain how a School SAC Score gets translated into a Final Score?


Coursework Unit 3    School Score 99       Final Score 100
Coursework Unit 4     School Score 98      Final Score 99


Thanks

PS: Also, is it possible that students can get moderated to over 100 in the final score in English?

Basically VCAA looks at how the average SAC score compares to the average exam score for some group of people within your cohort and check how accurate the SACs are to the exam. So if some group of people near the top end scored on average higher than their average SAC scores, their SACs would get moderated up.
So you or one ore more people closely ranked to you probably scored quite highly in the exam. Congrats

From what I know it's impossible to score over 100.

They either scale your school marks up or down depending on cohort strength and ranking within cohort.

Lets assume you were rank 1 for semester 1 and 2 for semester 2.

Some one got 100% in the exam or you did your score is scaled up since you were rank 1 (rank 1 receives exam score as sac score), eg 99 -->100

however you did  not receive rank 1 semester 2 so you receive a moderated score depending on your cohort strength eg scaled up to 98---> 99.

How they are moderated after rank 1 is too mathematical for me to explain. They also take gat into consideration but its not a major influence. i just want you to understand its not exactly your exam score.

so be proud of your cohort and im guessing your score aswell

Brencoookies explanation is surprisingly shorter and more thorough than mine. (surprised at how well you explained it with fewer lines than me lol)

Thanks everyone for your response.

Thanks. If it is impossible to get a moderated score above 100 in English then how can this subject have a mean of 67.1 and a standard deviation of 15.7?

In a normal distribution, 99.7% of the population would be within 3 standard deviations of the mean and 95% within 2 standard deviations of the mean. So the top range for 99.7% of the population would be 67.1 + 3 * 15.7 = 114.2.

The distribution isn't precisely bell curved .

That problem also occurs with study scores - the average is thirty with a rough Sx of 7, meaning 51 would be +3 Sx.

If you look at the graded distribution for English 2012, you'll notice it's less of a perfect bell curve and more skewed towards higher marks (for SACs), whereas the exam is closer to a proper bell curve.

Haha, I've just spent a year in uni trying to be thorough yet short! :p

Thanks! I looked at the 2012 graded distributions - a lot clearer now.
