Does that mean if you get an ATAR of 65, your aggregate is better than 65% of the state? If so, how come 65 is around the average? I've never quite understood why it's not 50
Just taking an educated answer to your question, remember that the AVERAGE AGGREGATE and the 50 AGGREGATE are two different things.
Remember that the average of a certain set of numbers is simply the addition of all of those numbers divided by how many there are.
Assume a "miniature victoria" home to 10 students who just got their atars. There atars were 30, 40, 50, 60, 65, 70, 80, 90, 95 ,99.95
When you average out these numbers, the AVERAGE ATAR AGGREGATE comes out to 68.
This is due to the fact that the amount of higher atars counteracts (to a certain extent) the amount of lower atars, to a point where the atar exceeds fairly above 50.
remember that the 50 AGGREGATE is where your smack bang in the middle. The average is a totallly different thing.
I think thats a good explanantion....
Anyways hope this helps!
