yep ive got one of those

 

[iambored]

do they check, since you're not allowed the fancy ones

 

[Orange Juice]

doubt it... they couldnt check the WHOLE theatre...

 

[Grizzly]

you dont do the exam in the theatre ?
I thought you do them in like your tute class... ?
so they can check your calc.

 

[iambored]

yeah, otherwise what's stopping people from getting fancy ones

 

[Orange Juice]

but arent all exams identical?
cuz itll be too easy to cheat then

 

[Grizzly]

Nah, u dont do them in your tute time, you do it in your lecture time, but in your tute class , possibly in a different room.

i think

 

[iambored]

oh that makes sense. but still, there are like 6 different lecture times, ranging through the whole week.

well for marketing, all 360ppl will do it inside mason

the catch is..everyone's test is different in a way...where it is the order of question, or slight change of data..so if u copy the person next to u..u mgh as well guess all of them

 

[iambored]

ok so they do change them a bit. it makes sense, but you have to hope they are all of equal difficulty

I just have to say that Stat really really really sux...like heaps.

It's the worse subject....

yes, yes it does.
i really dont understand that "z" shit. i dont get the same results on my calc as the eg's in the book...i dont know why.

if ur doing it for psych, do u have 2 do it for the full 3 years? or is it only this year? (plz let it b only this year!)

 

[golfstick]

i'm finding it easy but so fucking boring. if i didn't go to the monday lecture i could take a 4 day weekend. I'm going to start doing that soon methinks

econ110 and law113 are my hard subjects. especially econ110, it's a bitch

z? what's that? is that stat 170? and you need to work out your calcultor, it makes so much difference. maybe scan it and see if we can tell you which buttons to press, since the numeracy centre people don't always know

are you first year?

Stat 170 is just.... boring...

 

[golfstick]

using the Z table is just what they make us use because they don't give equations of curves and expect us to integrate

the lecture slides explain the concept very concisely. just remember that for whatever value you look up in the table (which z goes from 0 to 4), then the decimal is the proportion of the area to the RIGHT of Y. If z is negative, the decimal you find on the table in line with the absolute value (equivalent positive value) represents the proportion of the area to the left of Y. 1 - (table value) gives the proportion fo the total area on the other side of Y.

edit: haha just read the notes i think. just as well i'm not doing education i s'pose hehe

I know, i was thinking that, so much beter to tell us the equation of the curve and integrate it from whatever they say the X value is ( z ) .

stats go throughtout psy degree program

stats is way boring n sux balls!!!!!!!!!!

yeah is that true?! because this was similar to what we were doing last year, the whole area under the curve was reminding me of year 12. so it is year 12 simplified?

 

[-=«MÄLÅÇhïtÊ»=-]

no its not a simplified version of yr 12
they use z tables because these guys dunno how to integrate the normal distribution. the fn of a normal distribution (aka bell curve) pretty hardcore to integrate.
