Hello, I am trying to test some results I have for significance. It has been recommended that I use R and I am completely new to this.
Set-up: Groups: two groups of 8 subjects (16 total) Two conditions: alert and passive Measurements: responses for three different stimuli (A, B, and C) measured in each condition Experiment: Testing the order of conditions Group one: Alert A, B and C followed by Passive A, B, and C Group two: Passive A, B, and C followed by Alert A, B, and C Stimuli A, B and C are randomly interleaved in the experiment, does this matter in my ANOVA? I am interested in making a between and within group comparison of responses to A, B, and C <he>Here is what I am doing: My data is arranged in the following way Group Subject Condition Stimulus Response One S1 Alert A _Value_ One S1 Alert B _Value_ One S1 Alert C _Value_ One S1 Passive A _Value_ One S1 Passive B _Value_ One S1 Passive C _Value_ One S2 Alert A _Value_ ... Two S9 Alert A _Value_ Two S9 Alert B _Value_ Two S9 Alert C _Value_ ... This is the code I used: M400_500_anova = aov(Response ~ Condition * Stimulus * Group + Error(Subject/Condition * Stimulus ), data=My_Data) Is this correct? ANCOVA question I haven't gotten as far with this one, but I want to do an ANCOVA using the passive responses as a co-variate, but I am not sure how to even do this with so many factors/groups/repeated measures. I am also not sure what function to use in R, or how to even write the command. Thank you so much for your help!
