Abstract
One of the most important data in educational field is how children and pupils feel about the learning of individual subjects at school. Children from the third grade of elementary school and pupils from the first grade of junior high school were asked to rank the subjects, which they have been learning at school, according to six criteria such as the order of preference. The results were visually represented by the rank graph which could give the average and deviation of ranks simultaneously. It was discussed that the method of graphical representation of educational data are as useful to teachers as to children and pupils who have no knowledge about educational measurement and statistics.
