UAI is strange (1 Viewer)

[Survivor39]

hmmm, I want some professional opinion on this case:

Person 1 in my school (UAI 94.90)
Maths Ex1 91
Maths Ex 2 86
English ESL 85
Chemistry 78
Biology 90

Person 2 in my school (UAI 96.45)
Maths Ex1 87
Maths Ex 2 82
English ESL 88
Chemistry 76
Vietnamese Continuier 91

What went wrong here?

 

[abdooooo!!!]

the uai are very close... proly only 5 scaled marks between them in total maximum.

ESL english should be the main factor here...

let me illustrate this with the stastics, this year: 91 hsc mark gets you 92 scaled mark, while 84 hsc mark gets you 76.

this is a significant drop in scaled marks in that range, so the 3 extra hsc mark could've given the 2nd person an extra 10 marks.

and the rest of the subjects cancels down to about 5-10 scaled mark difference in favour of the 1st person.

so in the end is very close as indicated by the uai.

biology = bad scaler
but still far out that is unbelievable there a huge difference abdooo
maths 1 whoped 2 so i dont know???

il just go back to my uai is a conspiracy theory

nah... biology 90 hsc mark = 89 scaled marks

compared to vietnamese 91 hsc mark = 90 scaled marks

so they are similar.

the math difference is not big... should only be around 5-8 scaled marks.

so your trying to say that 3 marks in esl cause 3+ uai points in diference????

its 1.55 mate.

like i said that difference is only maximum about 5 scaled marks. could be as little as 2 or 3 scaled marks.

 

[sam04u]

wake up something has gone wrong.. look at the difference
4 extra marks in e1 4 in e2 and 2 in chem against 3 in esl and 1 mark in bio if scaling is as you said

The aggregate (total of the scaled marks) for Person 1 is about 415, and the aggregate for Person 2 is about 417.

I'm pretty sure the aggregate is what determines the UAI, so you can see that Person 2 would get a higher UAI.

Edit: Aggregates based on JUAISeek

 

[santaslayer]

yea thats what i was thinking...aggregate determined significantly to uai
although im still suprised with the
biology vs vi3t... which i would of thought vi3t would be a really low scaled sub

 

[pigs_can_fly]

aggregate of scaled marks mind you

 

[Newbie]

any continuer language should be higher scaled than bio

 

[Survivor39]

But that's only 2 units. And remember the scaling of 4 U maths and Chem from person 1.

 

[Newbie]

hmm
i suppose just glancing at the marks i would of said person 1 had the higher uai

yeah its weird

 

[Beaky]

UAC are strange people

we all know that

 

[freaking_out]

freaky results there- i guess it was mainly bcoz of the esl mark difference, and also the 91 in vietnamese could've helped as well. :s
