Abstract

Let us suppose we have two products or parties or opinion and a pool of small choises and we want understand if the preferences are changed with respect to fixed values. If the sample size is big we propose a two stages hypotheses test based on Duncan suggestion and improved in 2008 by Pollastri based on the distribution of the absolute maximum and minimum of the components of a bivariate correlated Normal r.v.. The critical values are reported.
