1. In the UNSW information evenings on youtube, do they actually show median ATAR's or is it averages, because there's like .82 and .57 popping up for local and rural offers.
2. If it was averages is it like incomes where the displayed average is going to be higher because of the higher marks "dragging" up the score? (like how average income is like $60k whilst median is around $53k)
its the median, the .82 comes from when there are an even number of offers, ie a guy with a 97.85 and a guy with a 97.8 would have been in the middle so the median was 97.825 which they just round down to 97.82 (dont know why they round down though).

1. You can have a median of .82 if there's two people with .80 and .85 taking up the middle spots.

2. You'd better hope the numbers shown aren't averages otherwise the situation would be a whole lot more bleak.

ATAR mean/medians work in the opposite way to income. For incomes, there's a lot more potential to expand in the positive direction - you can make $1,000,000 but you can't make -$1,000,000 despite both of them being equally far in opposite directions. As a result, the average income gets brought up by these anomalous high income earners while the median stays low.

In ATARs, there's not much potential to expand in the positive direction when we're already dealing with ATARs in the high 99s. The only direction is in the negative direction, which is why the average ATAR tends to be lower than the median ATAR, brought down by lower ATARs. You can have a 98 ATAR applicant, but you can't have a 101 ATAR applicant to balance it out.

If the AVERAGE ATAR is x, then the median ATAR is likely considerably higher than x.

Speculation: ATAR is in increment of 0.05 but GPA equivalent is not.

Speculation:
It is a median of selection rank on those studying in Year 1 and so there is a lower bound on it regarding median vs average.
