A note on the bipolar mean: is it a single mean?
| STATISTICA & APPLICAZIONI - 2008 - 1
In this note a generalisation of the bipolar mean, recently introduced in the literature by Maffenini
and Zenga (2005), is presented and discussed. It seems interesting in those contexts, where the categories
of an ordinal variable are to be thought as ‘‘non equidistant’’, like in some problems in the
customer satisfaction analyses. It is pointed out that the particular bipolar mean chosen for a problem
can modify the ‘‘ordering’’ among the frequency distributions with fixed sum N.
