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.

Abstract
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.
