Psychology AQA A PSYA4 18th June 2012!

Association is where you're looking to see if there's a relationship or correlation between two things. A difference is a.... difference. I'm not really sure how to explain that, haha! Perhaps someone else can help! :smile:

LOL right so a difference is a difference! Makes sense :biggrin:

kk so Association would besphearman/rho and chissquared, since you can/may be able to use corrlation on them.

Do you mean difference, within the numbers?

I think anti social behaviour, effects of television and attraction of a celebrity might come up (:

Thanks Anti Social behaviour would be an ok topic to come up. Also do you know if the decision making section in persuasion and attitude change has gone from the spec?
Thank you

I think it has been taken out, I've got the new AQA psychology book and that topic isn't in there at all and it is not on the specification but my teacher still taught it.

Thanks, we have also been taught it, but if it isnt in the new spec then i assume it must have been taken out. (hopefullt anyway as it is such a boring topic)

Ahh thankyou, that seems like a rather interesting way of doing things. :biggrin:

But may I ask what is
'Difference/Association)?

And is nominal-where it involves groups?
ordinal- is when it has a rank
intervaal-is meeasured in numbers?

Haha I can never learn things like a normal person :tongue:

It means if a study has found a difference or an association between two variables :smile:

(as in spearmans rho where the study must find a correlation for that test to be applicable)

And yep that's right :biggrin:

except ordinal data has a 'meaningful zero point' (I remember that by thinking of it as 0rdinal) - Basically if someone was rating someone on attractiveness (0-10 i.e ordinal data) and they gave them a 0, that would be meaningful as they are stating that they aren't attractive in the slightest :smile:

I think that's right anyway :/

That's right. Spearman's Rho and Chi Squared is for an association whereas Mann Whitney U and Wilcoxon are for a difference.

Difference refers to finding a difference between two conditions. For example, if you were looking at the difference between a treatment and a non-treatment group, then you'd use Wilcoxon or Mann Whitney U depending on the design. If you were looking for a correlation... between age and intelligence, for example, then you'd use Spearman's Rho (if it was nominal it would be Chi Squared).

Thanks, that's explained well.
Yeah it was quite funny as well 'men differ in intelligence' i will ddefo remmber that 1 :biggrin:

Lol right, i love your examples! So in the interval 0 can't exist?

Spoiler

Right so now I know that man whitney’s statistics shows it has a difference,it’s independence groups, and interval data.
But where does it show that in the question? :smile:

Haha! Oh crap, it's ratio where the data has a meaningful zero point, scrap that last bit :tongue:

Just got my work sheet out, It says:

Ordinal - the data can be placed in rank order (easy enough to remember, ordinal-order) but is measured on a scale of unequal intervals (scores on a test can be put in rank order, but we can't assume the intervals between each score will be equal).

Interval - This data has fixed intervals

Rati0 :tongue:

- same as interval but this is the one with a meaningful zero point.

Hope that makes sense :/ Glad you asked that, I didn't know ordinal was in rank order before looking at my sheet :tongue:

Hey, i'm currently revising for the schizophrenia topic I have two questions :P,

1. I was wondering if for the biological therapy section if anti-psychotic drugs and ECT counts as an answer, or if its just for a biological treatment kind of unsure on this :/

If not can you mention some sort of biological therapy's that can be added if there was an essay on this.

2. This follows on to my second question, can an answer for example be 'Outline and evaluate a biological therapy' or will it be more open so that you can talk about psychological, psychodynamic/ cognitive.

To answer your first question-both of those you mentioned, antipsychotic drugs and ECT can both be used as an explanation for biological therapies-its actually the main ones.

To answer your second question-they can pretty much ask us how they want- they may specifically ask for biological therapies or psychological ones.
or they may ask a open question such as outline therapies for schizophrenia and you can use either or both.
hope that helps? :smile:

So ordinal is like <-- bad, indifferent, good, satisfactory, fantastic??

interval is numbers...but 0 means something when it's ratio <--does that mean ratio as in 1:3

haha no worries. :smile:

(sorry again,just tryna does some revision on here)

Well let's break it down...
It's a difference because we're looking at the difference between eating a breakfast and not eating a healthy breakfast. We're not looking for a correlation between the two conditions.
They're independent groups because there's two conditions - eating and not eating.
It's interval data because she's looking at the childrens' reading speed (as mentioned in the first paragraph) - time is a unit which is at intervals.

If you wanted me to confuse matters, I could argue that interval data CAN be treated as ordinal too. In that respect, you'd still find that Mann Whitney U was the appropriate test due to it being a difference and independent groups.

I think that's all right, but I'm sure someone will correct us if it's not! Hope that made sense! :smile:
