    too high CV




    Hello friends, when i am analysing my data using ANOVA, i came up with a very large cv(55) is there any means to lower it? my design is 4x5 CRD with factorial arrangement.

    the SAS out put is this
    R-Square Coeff Var Root MSE LN Mean

    0.516573 55.69053 1.842112 3.307765

    Is your data interval or ratio scale? CV should only be calculated for a ratio scale. It has no real meaning for an interval scale, in which zero is an arbitrary value.

    yeah, my data is percentage data. i have counted and converted to percentage. I think i shall go for arcsine or square root transformation but still my CV is too large

    By percentage data do you mean you have something like a total number of attempts and a total number of 'successes' for each observation? Or was the percentage based on something else?
    I don't have emotions and sometimes that makes me very sad.
