1. A method for obtaining an indicia indicative of a spread of parameter frequencies within a computer system defining a resultant final indicia of a histogram spread, wherein said computer system includes a computer usable medium having a computer readable code, the method comprising: establishing a computer processor; providing a computer program to selectively define psychographic profiles for distinguishing between respondents to a plurality of psychographic queries, the computer program having modules configured for: compiling a plurality of frequencies of alternative responses to each said psychographic query obtained from members of a population of users to form a histogram of more than two bins representing the alternative psychographic responses, said responses corresponding to characteristic data for respective segments of the population; applying a plurality of statistical functions to said histogram for determining frequency characteristics of said responses within said histogram; applying a weighting factor to at least two of said statistical functions for indicating a spread of a histogram for each of said statistical functions to provide a plurality of weighted outputs; combining said weighted outputs corresponding to each of said statistical functions for determining a final indicia of histogram spread for the responses to each said psychographic query; selectively generating at least one wedge variable responsive to comparative analysis of said psychographic queries in said final indicia thereof, said wedge variable corresponding to a psychographic query evoking a histogram having a substantially flat or multi-peaked distribution for maximizing a disparity of psychographic responses by the respondents for separating the population of users in corresponding ones of said segments; and, outputting said final indicia of histogram spread to: (1) a computer peripheral device, or (2) to a computer processor program for compiling subsequent responses.
