An information processing apparatus obtains a plurality of attribute datasets including a subject attribute dataset, which are each a combination of a plurality of item values, and information indicating an area range that is taken as a target in a dimensional space. The information processing apparatus then performs a determination process of determining a change-target item value to be changed from among the plurality of item values of the subject attribute dataset and a changing direction for the change-target item value on the basis of the distribution of at least some of the plurality of attribute datasets in the dimensional space. The information processing apparatus outputs information indicating a result of changes made by alternately iterating a changing process of changing the change-target item value and the determination process that follows the changing process until the subject attribute dataset is within the area range.
