how long should we spend on the design of a study question because I am doing a question and it's nearly taking me 40mins to complete - I spent 5mins planning (it is a 10 marker, which says I need to operationalise the IV and DV and say how I should control the extraneous variables and says I should make the procedures and add sufficient detail so it can be carried out)? Also, when the question does not refer to the 'justify your choices' statement (this was the circumstance for the question I referred), do you justify them or not because how will you be able to get marks?
I would spend about 15 minutes on the question (including the planning) and I would always justify your choices just to make sure what you are saying make senses in context of the question. Obviously this is just my opinion, so just do what feels right to you
Yes I agree. Spend about a minute or so planning and about 15mins writing. Justifying your choices is always a good idea, even if it not specifically mentioned because you want the examiner to see that you know why you are doing what you are doing.
You could do, as part of controlling variables. But you have to think about whether a single/double blind makes sense in the study you are conducting because you always have to justify your choices.
Probably. When I think of likhart scale, I think of participants given many choices such as neutral, slightly positive or very positive. I think that may be the most effective way to use it.
As a general rule it’s: Nominal data: mode Ordinal data: mode/median and the range Interval: mean and standard deviation. However there are cases when you might need to deviate. Eg. If there are outliers you may not use the mean because it would skew the results.
Initially looked at this question and panicked but this helped a tone, thanks!
this was a life saver. thank you!!
You’re very welcome.

great vid
So useful! Thank you very much!
Why would you use the mean and standard deviation for interval data? And when would you use the mode?
you're my psychology king
😁 Thanks. Glad I can be helpful.
Thank you very much for this, its been v helpful:)
You’re welcome. I’m glad it’s useful.
For the design part, do I have to mention single blind or double blind as well?
You could do, as part of controlling variables. But you have to think about whether a single/double blind makes sense in the study you are conducting because you always have to justify your choices.
This was a really helpful video, thank you!!
This was so useful! Thank you so much
Thanks for your comment. Glad I could help.
great video, thanks
My pleasure. Glad it was useful.

so helpful, thank you!
Thank you
You're welcome
for 7:07 what should we use for norminal data?
The mode.
@@smcartledge2723 and for dispersion would range be best?
Do you think it’ll be a design a study this year or a different kind of question like consent/debrief form ?
I think it could be a design a study. But who knows.
So helpful
Is this in AS too?
5:43 is a rating scale the same as a Likert scale?
Probably. When I think of likhart scale, I think of participants given many choices such as neutral, slightly positive or very positive. I think that may be the most effective way to use it.
what descriptive statistcs to use for nominal data
As a general rule it’s:
Nominal data: mode
Ordinal data: mode/median and the range
Interval: mean and standard deviation.
However there are cases when you might need to deviate. Eg. If there are outliers you may not use the mean because it would skew the results.
@@smcartledge2723 thank you!
@@smcartledge2723 So if there were outliers would you use the median or mode?
