Hello,
Because of my very limited statistic knowledge, I would like to ask
about your opinion on what calculations I should do?
As part of a Psychology course I conducted a study (with 45
participants) in order to study something called promising alternatives.
I via a think aloud method retrieved participants ideal alternatives
about cars and based on it I developed 5 cars that were very similar to
their ideal alternative but differed a bit. I showed the cars as a
diagram where it consisted of several attributes such as size price etc
and each attribute had a value from 0-100 that was shown as a bar on the
diagram. (So I showed them five diagrams that each represented a car).
They were then asked to pick the most promising one. I repeated this set
of five ten times and each time I timed them on how long it took till
they picked the car that they found most best Each car I showed then
represented a decision making rule. So Now I want to see which rule they
used mostly and see if time has an effect. Of course I can just do a
frequency calculation but what should I do if I want to see if it is so
called statistically significant? Should I do a chi square? ANOVA?
Independent T?
Also how should I consider my data, because the way it is now is I can
do it in 2 ways?
1. see which rule each participants used as most and then see which rule
was most common out of the45 participants.
2. see which rule was used mostly in all the sets, meaning taking 45
participants x 10 sets and see which was most common out of 450.
Thank you in before hand |
