GCE A level result 2019 @ 22nd Feb 2019

I got confused with all the mean(average) and median UAS.


Median UAS is the UAS at the 50th percentile and mean is the average UAS.

Based on historical data, is median UAS usually higher than mean UAS?

So RI mean UAS is 84.5.
NYJC median or mean UAS is 85.X?

Then NJC median UAS is 84.4, so what is its mean UAS?

You are right. median is usually higher than mean based on historical data. NYJC median is probably around 85 since they said 50% of their students attained more than 85 UAS. So, at 50 percentile, it stands right at 85.

NJC median UAS is 84.4. Mean should be lower than that, usually 1-3 points lower. these number is quite credible as NYJC cop in recent years is 7 while NJC is 8. So, njc attaining slightly lower result is about right.

I am very surprise someone posted NYJC's results as below

H2 Maths: >70%
H2 Chemistry: >70%
H2 Physics: >70%
H2 Biology: >70%

It is better than RI since RI's result for these subject is 70%.

agree.

Something don't seem right, with above data posted, for Nanyang Junior College, H2 (Maths, Chemistry, Physics, Bio) Maths and Sciences subjects. The figures posted, somehow don't seem to be reliable, like can't be trusted ? Maybe out of the 4 H2 subjects posted, perhaps one or two subjects could be > 70 %. But, doubt that all the 4 H2 subjects are > 70 %, each.

I think likely the interpretation is from the NYJC P's youtube sharing. He said, \"For Maths and Sciences, more than seven out of ten of you scored distinctions\" (about 45s into the clip). But that sentence is so ambiguous. More than 7 out of 10 of the students scored distinctions for math and sciences, does it mean >70% of students scored at least 1 distinction in Math/Chem/Phy/Bio? H1 or H2? This is very different from saying that 70% of the students scored distinctions in each of the four H2 subjects....

Actually the 2 main stats are the mean and median UAS. All sch should at least share one, if not both of them. The rest of the stats are more or less peripheral.

The best is to state both mean and median UAS clearly out-front, dont make parents guess is it mean UAS or is it median UAS.

IMO, I guess not many Ps wish to be so transparent.

Anybody has studied whether the COP ranking corresponds to the schools’ A level performance?

As I said earlier...

It's easy to be transparent when you are heads and shoulders above everyone else.
For the rest... always highlight the good points, muddle the good-but-not-so points, ignore the weak points.

That's my interpretation as well.
Instead of:
H2 Maths: >70%
H2 Chemistry: >70%
H2 Physics: >70%
H2 Biology: >70%

I believe it's more likely:
More than 70% has an A in either one or more of Maths / Chem / Phy / Bio

I want to applaud RI/RIJC for, once again, encouraging rafflesians to realise their academic potential to the maximum allowed by MOE, ie 13 units.

6 pupils scored the maximum 9As.

Do you know this year in total how many students achieved 9 As?
