Abstract
A product discriminating device that includes a measuring section, a discriminating unit, a deemed standard deviation calculation unit, a re-discriminating unit, a rank estimated number calculation unit, and a standard deviation calculation unit. The standard deviation calculation unit changes variables of a probability distribution of a deemed standard deviation such that the number of products belonging to at least one of a predetermined plurality of ranks re-discriminated at least once and an estimated number of the products belonging to the rank in a rank estimated number calculation unit substantially match each other, and calculates the changed variables as a standard deviation of characteristic value variation of the products and a standard deviation of measurement value variation.
