I am not sure how to perform the statistical analysis on the following table.
I did an experiment in which 12 participants had to choose between 3 conditions when provided with 3 stimuli.
Stimulus Condition1 Condition2 Condition 3 A 9 1 2 B 10 2 0 C 8 2 2
I want to prove that it is not by chance that Condition 1 is preferred rather than the other two conditions. How can I do this analysis? Maybe with a Chi Square test? If yes should I group Condition 2 and 3 against Condition 1?
I use R, in case could you please provide an R example in order to analyze these data?
Thanks in advance
