Help- operational hypothesis.

[littlebecc]

Hey guys, if you have a grivas text book, would you mind helping me out on this?
I'm doing my ERA tomorrow and on page 407 of the text book is the era.

I'm having trouble with the operational hypothesis- it sounds really confusing right now and i was wondering if anyone could help..

Here's what I got: It was hypothesized that VCE psychology students from (my school) will remember more word pairs and have a more accurate transfer of information to long term memory using elaborative rehearsal, which involves taking about 10 seconds to form a mental image after counting backwards by threes from 1113 for about 30 seconds, than compared to those who used maintenance rehearsal by repeating each word pair aloud five times to try to transfer information to long term memory.

What do i need to add/takeaway/make it look better.
Taa!

[studying_hard]

sounds good. Is "VCE students from your school", the sample or population? It should be the population whatever that is. Maybe if anything there is too much detail if anything. Maybe revise "which involves taking about 10 seconds to form a mental image after counting backwards by threes from 1113 for about 30 seconds" as I do not believe it is neccesary to include all that. hope that helps somewhat

[littlebecc]

she said to put 'which involves taking about 10 seconds to form a mental imag' but maybe i'll discard the 'counting backwards by threes'?
Yeah i agree, it seems to long. I don't know which bit to shorten coz i'm scared if I do i'll leave something out!

edit: vce students is both the population and the sample...actually technically '14 girl psychology students is the sample' so i suppose vce students is the population?

[littlebecc]

wait, is this better/neater?

Operational Hypothesis: It was hypothesized that VCE psychology students from -insert school- will have a more accurate transfer of information to long term memory using elaborative rehearsal in a 30 second time frame, which involves taking about 10 seconds to form a mental image of each word pair, compared to those who used maintenance rehearsal by repeating each word pair aloud five times to try to transfer information to long term memory. 

[Spreadbury]

regarding this, I would say "the transfer of information from short-term to long term memory" (do be specific as possible) and when mentioning that the second group will use maintenance rehearsal, don't say "those" say "VCE psychology students from -insert school-" as 'those' is pretty vague.

otherwise I guess it's pretty good. it does seem as though it's convoluted when describing the process but that's almost unavoidable for these types of hypotheses it seems. in my ERA mine sounded complicated, long and confusing too

[littlebecc]

Thanks so much spreadbury!

Operational hypothesis' are more detailed.. For full marks you should to include the following:

Population
Independent variable
Dependant variable
Extraneous variable
How the results will be recorded (driving test/ IQ test - relating to the scenario of course)

This is what I was taught, its also in my textbook.

Refer to this, Eriny is a beast at psych. 10/10.

[Spreadbury]

How the results will be recorded (driving test/ IQ test - relating to the scenario of course)

definitely. can't believe I forgot that

[Hutchoo]

Its probably the most important factor for the whole operational hypothesis.
Just make sure when you write them that they're full of detail and very specific, don't be ambiguous with your sentences.
Try and get straight to the point.
IV and DV are most important, you ALWAYS have to make sure its in the operational hypothesis.

All of the things I said earlier should get you full marks.

How the results will be recorded

soo...the marks will be written down? how do i include that in my hypothesis.

Well your comparing elaborative and maintenance rehearsal...so how are your measuring which one is better? Mean score across the groups of items recalled? etc.

[littlebecc]

Mean score across the groups of items recalled? etc.

Ohhh right. I didn't know this had to go in our operational hypothesis? I put all this mean information in my results area.

[Hutchoo]

 It was hypothesized that VCE psychology studentspopulation from (my school) will remember more word pairs and have a more accurate transfer of information to long term memory using elaborative rehearsal, which involves taking about 10 seconds to form a mental image after counting backwards by threes from 1113 for about 30 seconds, than compared to those who used maintenance rehearsal by repeating each word pair aloud five times to try to transfer information to long term memory. These results will be recorded by the VCAA accurate long term memory test.

Or something like that.. Its best to actually relate your results to the scenario as it seems more professional, and the more professional the better. e.g. A scenario based on P plate drivers etc.. You can use something that relates to it like "The results will be recorded by the RACV road safety driving simulator"

[bomb]

No put the actual info in your results..heres a good example of one: (from VCAA 2008)

For first year psychology students from Kookaburra University, learning ability – operationalised as the score on a
memory test of 20 words – will be more improved for students who consume a sugary drink than for students who have
a drink containing no sugar.
An operational hypothesis is a stated prediction of the outcome of the experiment that includes:
• statement of the population
• statement of the independent variable (IV)
• statement of the dependent variable (DV)
• operationalisation of the dependent variable.

How the results will be recorded

soo...the marks will be written down? how do i include that in my hypothesis.

Well, something like marks will be written down is usually part of the procedure section.

What I think Hutchoo means is that you need to define how exactly are the concepts that you've mention going to be measured.
