DATA ANALYZING DEVICE AND METHOD, AND PROGRAM FOR MAKING COMPUTER EXECUTE THE DATA ANALYZING METHOD

To provide a data analyzing device and method and a program for making a computer execute the data analyzing method for efficiently extracting data distribution information. A grade of unity represented by the following expression is derived for each of (the number of small sets Gj−1) combinations Ak.Grade of Unity=[{S0−(S1+S2)}/S0]×100 In the above expression, for example, S0 is the sum of deviation squares of the object variable (temperature T1) of m records Ri, S1 is the sum of deviation squares of the temperature T1 of the records Ri belonging to the large set G′1k, and S2 is the sum of deviation squares of the temperature T1 of the records Ri belonging to the large set G′2k.
