Coefficient of variation and consistency?

  1. May 8, 2013 #1
    The coefficient of variation tells us about the consistency in the data. I know that the lower the coefficient of variation is, the higher will be the consistency in the data. What I don't understand is what is being meant by 'consistency' here. Could someone please explain that?

    Consistency in data means less diversity. It describes the scatter or dispersion of a distribution.

    In some applications in physical sciences, low but noticeable variability in data may confirm the presence of random measurement errors, in which case one may assume that the quantity being measured is in fact stable, and that the variation between measurements is only due to observational error.
