<p>The invention is a valuation assistance system that enables a user to more precisely, accurately and simply assess a value disparity between products or services before purchase. The invention is provided with: a valuation server that determines the statistically significant difference for a value disparity between items to investigate, and outputs a result; and a user terminal. The valuation server comprises: a valuation information input unit that receives input of valuation data related to the items to investigate, and stores said data in a valuation history database; a valuation history information acquisition unit that extracts valuation data from the valuation history database, for each valuation indicator, for each of multiple user-selected items to investigate; a statistical calculator that determines the statistically significant difference between the items to investigate, using a statistical calculation based on ranking data computed by a predetermined procedure on the basis of extracted valuation data; and a valuation result output unit that outputs statistical calculation result information to the user terminal, along with recommendation information related to a value disparity assessment standard selected on the basis of information indicating the statistically significant difference between the items to investigate.</p> |
