Possibility of Study Score Calculator?

[kingmar]

I want to propose an idea, I'm sure we've all had it...

No-one has managed to come up with a Study Score calculator yet. But how would this work?

Consider this. Study Scores are normally distributed. Correct?
Thus, if everyone from this year gets statements of study scores, we can possibly plot points and get an estimation of what is needed for a certain study score. Not to mention, mid-year VCAA release their mean and standard deviation statistics.

If we get a sample of like 5 study scores or ranges of marks for a certain study score, does anyone think it possible that we can normalise these marks ourselves and predict study scores?

Just a thought.

This wouldn't work for Chemistry or English by the way, as the study design is changing too much for old stats to be relevant.

difficult because it dpends on difficulty of the exams as well as strength of the competition. Also some scores mark sacs harder than others ( But i dont know if we rank according to schools in victoria )

[Odette]

Yeah i'd like someone to create one, but it would be hard too many variables.

[kingmar]

The scores reported in the SoS are moderated already.

Thus, it's easier to normally distribute. But, I'm not the maths whiz here. All we'd need are like 4 reference points - we could estimate the rest reasonably accurately. After all, all you need are two sets of points to determine mean and SD.

VCAA provide these statistics in due course. When they are released, we can make an accurate guess, I presume. But I need data.

[Galelleo]

Yes thats true, we could create an accurate calculator for last years data...but this years scaling, difficulty, competiion is all going to change. Eg the exams are different difficulty, hence subject scaling AND score skew is different... as well as the people themselves being different.
But youre right, we could probably get a really rough indication./

[kingmar]

Cohorts don't change much between years.

What we derive in one subject we can relate to similarly scaled subjects, such is the nature of scaling.

Which is what makes this great. BM can be likened to H&HD, Eco can be likened to Accounting.

Yes, the ranges all differ. But proportionally, we can thus make an accurate estimation, as opposed to a random guess out of the blue.

Just calculate your STUDY using normal distr, by percentage of doing well.

mu = 30
sd = 7

Pr(score <= X) = 0.85, top 15%
X = ~37.25.

Gonna have to use grade distributions to find percentages of people who got A's etc ..

Yes, that was what I was referring to.
But specifically, that doesn't tell you what kind of EXAM SCORES you would need to achieve, or scaled SAC scores.

Which is my aim after I'm done with this pain in the arse here named VCE.

or...you could just study really hard and let VCAA do all that.

That would probably be unreliable, as the sample size would be too small.

"textual abuse"

You don't like me much, do you? :cry:

Have a look at all the "predict my study score" threads out there.

If we got some semblance of a table going, it would help them greatly.

I'm only trying to help. Genuinely help, as opposed to your put-downs and unconstructive comments.

Don't tell me, tell all those people out there that go on about what study score they want. It's a service I'm thinking about. You don't have to use it if you hate it or me so much.

That would probably be unreliable, as the sample size would be too small.

It would be more reliable than plain guessing at study scores as per all the thread predictions we have going on.

It's a thought. If there's too many doombringers or negative opposition to it (can't see why, but still), then I won't bother.

[Galelleo]

uh... theres no dislike, OR put downs in any post on this thread...

[kingmar]

Tell me when rustic_metal has said something useful in response to me, and I'll eat my chocolate hat.

If you can't, I'll eat it anyway, because it's chocolate.

EDIT: Ask him. I reserve my judgement, and I will not talk about it further.

Now, back on topic...

Anyone care to get Statements of Study Scores? Mine won't suffice on its own. At least two are needed to predict means and SD's, not to mention making generalisations. Five as a minimum is preferable.

[Galelleo]

lol, not being useful isnt the same as put downs and dislike.

[Odette]

good idea
