[Challenge] It is aimed at enabling market research and analysis with high accuracy. [MEANS FOR SOLVING PROBLEMS] A market research and analysis system (1) comprises waveform generation means for waveforming customer data stored in a database, means for calculating a difference between points of at least two waveforms generated by the waveform generation means, Means for calculating a difference between segment angles of at least two waveforms generated by the waveform generation means; means for determining whether a difference between the points falls within a threshold value; Means for calculating a ratio at which a difference between the points falls within a threshold value; means for calculating a ratio at which a difference between the line segment angles falls within a threshold value; And a ratio of the difference between the line segment angles within the threshold value to an approximation of at least two or more waveforms It has means for calculating.
