hello friend,
I am undergoing a mental breakdown since I cannot find my way out of this problem. I'll give a short preface of the subject for those interested.
Writing a paper on prototypes based on: Posner & Keele / Smith & Minda. (for a school project testing our ability to write papers.)
based on their research we were given random data in which we have to test two hypotheses/
a) prototypes and old variables yield no significant pvalue
b)prototypes have a shorter reaction time than new variables
C) old variables have a shorter reaction time than new variables
data given:
24 participants
3 conditions tested per participant
each condition has 22 items.
measurement= reaction time
we want to do a paired ttest and an independant ttest, but we do not know how to test this.
by using R, we can do a paired ttest (withinsubject) but only per participant.
how can we include all observations from all participants to do a between subject ttest?
If I wasn't clear enough or you have questions you can contact me here or ask for my email.
thanks in advance,
VUB
