Analysis of "variance" for qualitative data ("mutability analysis")


A decomposition of an appropriate qualitative variation index (essentially a measure of entropy) is pointed out
(this is similar to the well known decomposition of variance, but for nominal variables):
Total Variability = Variability within groups + Variation between groups
and, most importantly, a simple and suitable distribution of the test statistics is derived.
This allows to treat quantitative data with a conceptual approach analogous to quantitative data, and the test is very simple and effective to carry out.
