PROBLEM TO BE SOLVED: To determine whether the data point distribution area is distributed in a specific determination area, in a state where the amount of information for expressing the data point distribution area is made small on a coordinate plane.SOLUTION: A determination area is set on a coordinate plane on which data of a data group determined as including a plurality of data having a paired two variants are expressed as points. An area on the coordinate plane is divided into two or more divided areas, radially from a division center point as an optional point of the area. A data point having the greatest distance from the division center point in each of the divided areas is selected as a representative point of the data point distribution area. It is determined whether there is an overlapping area where a distribution representative point area is coupled by a line and formed overlaps a determination area. When there is overlapping area, it is determined that the data group to be determined is a relevant data group. |
