    Multiple Measures (Different Variables) from Same Subjects




    Hi all!

    This is my first post. I hope someone can offer advice!

    I have a student with a seemingly simple analytical problem but I cannot figure it out. She has one group of subjects from whom she has taken a measure on eight (8) different quantitative scales. The scales are related, in that they can be compared, but it is not a "classic" repeated measures situation, as each measure is a different variable, not multiple measures of the same variable.

    She wants to compare the means on all possible pairs of the eight (8) variables, and has performed the 36 t-tests required.

    This doesn't seem right!!

    I have considered treating each variable as "repeated," but there is no independent variable; there are just the eight (8) means. Also, I have considered treating the scales as groups of an independent variable, but the groups would not be independent.

    What's the solution? Does she do the multiple t-tests and apply some type of correction for familywise Alpha?

    Any ideas appreciated. Probably something simple that I am missing!

    Thanx!

    What is the purpose of the analyses? What do want to find out or what hypotheses do you have?

    The Ho is that there are no differences among the mean scores on the 8 scales.
