hmmph. 100 students for all the year 4 victorian students i would have considered a bit small, but if you say so.

Yeah,  100 out of tens of thousands of people, seems quite small to me.

Well, obviously the more people the better, but in generally, with the sort of statistical methods we can use to analyse the data, you'd only need 30 for them to be valid usages of the hypothesis tests (e.g. Student's t-test).

You got to remember that the more people you have in your experiment, the more $$$ it's going to cost (and other things like drop out also may cause problems). 100 people in an experiment such as this would probably be considered a fairly large-scale study.

41-46. not knowing your mid year A+ makes it difficult

for the question what are the 2 things need in the debriefing i said
1.explain about the purpous of the experiment
2.explain about the results obtained

would this be correct?

i don't think 2 is, as explaining the results obtained would be in the actual report made later, right after the experiment one is debriefed about the true nature/aim/purpose of experiment and clear up any misunderstandings, also ensuring one leaves in the same physiological and psychological state they arrived in.

Outline one uncontrolled variable that could potentially confound the results and describe how it could affect
the results.
for this question i said that as the teacher was obtained the results she may have unintetinally favoured some students causing ineffictive results would this be right

[ayaz]

just wanted to know for the question that say were the participants randomly allocated and what is random allocation
(2 marks) if i said NO but correctly explained what is random allocation would i get (1 mark)

yeah you'll get the 1mark

[samuch]

yeah it did
EDIT: it used random allocation.. but didnt use random sampling.. i think you may have confused the two

[ayaz]

hey just wondering is an 82/90 still be counted as an A+....or would it be a high med low A

thankyou everyone

[samuch]

if its not a low A+ then it would be a high A

[Saraime2003]

According to these marks, i have 82/90 as well. thats being harsh too cos when i was marking SA if i wasn't sure if my answer would be right i didn't give myself the mark. hopefully thats another A (a high one *fingers crossed*) because if i have A for mid year, A for end of year and A+ for SACs i might get 40. But knowing my luck, because i want 40, ill get 39. lol

mm, im hoping for an A+, dont know if that will be possible but lets not burst my bubble yet. haha
and what study score would you neeed for it to remain the same and not scale down?
