PROBLEM TO BE SOLVED: To enable simple grouping without performing complicated statistical processing even in a case where there is deviation in distribution of an input measurement value group.SOLUTION: A measurement value classification device stores in processing parameter storage means end values that dispose of elements, which are extreme values and are not suitable for statistical processing, and the number of the end values as a processing parameter; sorts measurement values in an ascending order; disposes of the measurement values of the end values by the number of the end values, in the number sequence of the sorted measurement value; compares the difference between adjacent measurement values of the number sequence; determines the adjacent measurement values to be in a different group when the difference is larger than a reference inclination, and determines them to be in the same group when the difference is equal to or less than the reference inclination; classifies the measurement values into a plurality of groups; and calculates the number, average value, minimum value and maximum value of elements in a group to output them. |
