PROBLEM TO BE SOLVED: To visually display correlation rules extracted from a plurality of data groups so as to detect a difference in the correlation rules of data groups. SOLUTION: Original data are divided into a plurality of data groups Di (i=1, 2,..., n), correlation rules are extracted from respective data groups Di, the data groups Di are statistically processed by using variable to be explained, condition part items and result part items as explanation variables, condition part scores bj and result part scores hj are added to respective items j (j=1, 2,..., m), and the correlation rules extracted from respective data groups Di are displayed on the same xy coordinates by using the scores bj, hj added to respective items j as x and y coordinates values to visualize differences in the inclinations of the data groups Di.
