Abstract
In the field of computerized English teaching, whether CAI, CALL or CMI, there arises the problem of representing numerical data in a form which can be easily grasped by both students and teachers. This is because the amount of accumulated data becomes so huge that it sometimes is very difficult to discover the tendency hidden in the data. In this article, some ways of graphically representing numerical data already installed in the CMI system developed by the author are reviewed, and the possibilities of a new method called Chernoff Faces, introduced to deal with the problem of representing the results of questionnaires, are explored.
