Title: Help- operational hypothesis.
Post by: littlebecc on October 13, 2010, 05:28:19 pm
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!

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

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?

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.

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 :D

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.

definitely. can't believe I forgot that

Post by: Hutchoo on October 13, 2010, 09:04:35 pm
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.

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.

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

 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"

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.

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.

Yes, thank you :P Sorry- I'm not very good at explaining some concepts.

so the operationalisation of the dependent variable would be (for example) These results will be recorded by the VCAA accurate long term memory test. ?

So would i put in there something like....specifically the recall of how many words can be remembered and associated. ??

No that's not it. You don't have to mention how the results are going to be measured.

What you have to said is that you have to state the hypothesis that makes it tangible or concrete, so that a person could read it and get an idea on how you intend to measure the concept your experiment is about.

Yeah something like that.

Try if you can put it into the sentence itself, doing things like dashes is seen as a bit too informal for this sort of writing.

yep, bomb. that's what i added too.
Thanks so much for your help guys! Swear i wouldn't know what i'd do without this site.
Cheers!

glock- how about...

: It was hypothesized that VCE psychology students from -SCHOOL will transfer information from short term to long term memory more accurately 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 VCE psychology students from -SCHOOL- 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 how many word pairs can be remembered and associated.

Id change that to:

It was hypothesized that VCE psychology students from -SCHOOL will encode information from short term to long term memory more accurately, hence recalling more of the word pairs correctly, using elaborative rehearsal in a 30 second time frame, which involves taking approximately 10 seconds to form a mental image of each word pair, compared to VCE psychology students from -SCHOOL- who used maintenance rehearsal by repeating each word pair aloud five times to try to transfer information to long term memory.  


Or a new one:

It is hypothesised that VCE Psychology Students from (Sch) will encode information to LTM more efficiently using elaborative rehearsal by visualising each word pair for 10 seconds, and hence recall a higher proportion of words, as opposed to students who use maintenance rehearsal by repeating each word pair aloud five times.

Think of the IV and the DV as a television with bunny ears as its antenna.
(http://img64.imageshack.us/img64/9448/arr.png)
IV = the bunny ears, you can change the bunny ears around- meaning the IV in an experiment is something that can be controlled/changed.
DV= The actual picture given from the bunny ears, the DV cannot be changed, meaning that the DV in the experiment is a result..
For example:
Students who study while listening to classical music tend to get higher study scores for psychology than those who don't.

IV= Music that is being played etc.[Things that can be changed]

DV= Result of the students. [Result]

EV= How loud the music is played... What artist they listen to etc. [EV are factors that can change the experiments DV]



Just a revision if you're not 100% sure on what an IV/DV/EV is.

I'd go with the bottom one actually -> it's reads a lot easier than the first one which is bulky and hard to read.
