Is the ENTER CALC really accurate????

[Fyrefly]

My scores made 98.95 on the calculator, I win

Ha ha, bad luck Jamison! XD

I got 97.35 (but I was '07er).

It's true that it's a little bit off in some places.  The 99.95 cutoff on the Calculator at the moment is something like 211, whereas last year it was possible to get it with around 208.5.  Nevertheless, it's pretty damn close most of the time.

True.  In any case, Daniel did mention at the top:

ENTER Calculator is a website that will allow you to estimate what your VCE ENTER score will be.

He didn't say it was 100% accurate.

Mine's off by 0.05 also =T I have a feeling it's more accurate the higher your ENTER is though, since the scaling gets smaller with higher study scores which leaves less room for error.

yeah at the moment the gap between 99.90 and 99.95 is massive lol

[Davoo!]

The ENTER calc is my favourite toy.

I just love typing in 35 raw for all my subjects and seeing 94.05 popping up. LOL.

[ReVeL]

My calculated ENTER is 0.15 above my actual ENTER.

Interestingly, the 2007 data predicted my ENTER 100% accurately.

Hi Guys 

Last year i had some friends who graduated YR 12 successfully....

They typed there study scores onto the ENTER CALC and got a higher score than their actual ENTER.

IT WAS OFF BY 2 OR 3 PERCENT....


And same happened to my other friend?
Is this program not exactly accurate?


Regards,
 

The program isn't accurate to the dot (but something closer to the figure is basically there)

I checked mine just then:

I got an ENTER of 89.45 and it predicted an 89.70

ok.

About .2 off. I'm guessing it's because the real ones have all these decimals and stuff but the estimator is just whole numbers.

Yeah, I think that's it. The scaling report lists whole numbers for what 25, 30, 35, 40, 45 and 50 scale to, but the actual scaling is done with decimal values. So my estimates will always be slightly off, but should still be okay for most people

Oh, it looks like the data wasn't updated fully :| Just noticed now
The lower aggregates were correct, but the calculator has 210.9 as the 99.95 cutoff, whereas the 2008 data lists 209.3. Will fix.

I have read that you used a linear model to approximate the scaling. That can also contribute to the variation. The actual scaling (I assume) would follow the same shape as a normal distribution.

The Entercalc will be more accurate for higher ENTERs as compared to lower ENTERs as the possible aggregate difference between those higher ENTERs is larger and so larger error is accepted.

Yeah, I don't really have the skills to do it any other way... I wouldn't know how to do it
