    Choosing right ANOVA & how to input data




    Hi,

    Need help with an issue. I'm not quite sure how to input the data I've collected and I'm guessing I should use ANOVA RM, but not 100% sure about that. Anyway...

    One group of subjects (N=10) has been tested three times (three exercises) and I've measured activity of the pectoralis major and deltoid using a total of 8 electrodes.

    So each measurement/exercise provides 8 data/results.
    (p1-p6 data from pectoralis, d1-d2 data from deltoid)

    The data is as follow
    Subject1 ->exercise 1 -> p1, p2, p3, p4, p5, p6, d1, d2
    Subject1 ->exercise 2 -> p1, p2, p3, p4, p5, p6, d1, d2
    Subject1 ->exercise 3 -> p1, p2, p3, p4, p5, p6, d1, d2

    Subject2 ->exercise 1 -> p1, p2, p3, p4, p5, p6, d1, d2
    Subject2 ->exercise 2 -> p1, p2, p3, p4, p5, p6, d1, d2
    Subject2 ->exercise 3 -> p1, p2, p3, p4, p5, p6, d1, d2

    Subject3 ->exercise 1 -> p1, p2, p3, p4, p5, p6, d1, d2
    Subject3 ->exercise 2 -> p1, p2, p3, p4, p5, p6, d1, d2
    Subject3 ->exercise 3 -> p1, p2, p3, p4, p5, p6, d1, d2
    ............

    I want to analyze the data WITHIN subjects and I want to compare how p1 changes between exercises. For example, is p1 less activated in exercise 1 than 3?

    I attached a picture, that is how I wrote the data, not sure if it's correct. I haven't filled all the blanks because I just wanted to illustrate how the data could be put in.
    Sry if I'm being unclear and thanks in advance.
