The purpose of this study is to analze the result of the 1964 year Education Ministry Achivement Test for secondary school students in Hokkaido. The scores on the tests of the students whose parents belong to the following occupational groups (professional and technical, manegerial and official, clerical, agricultural, fishing, and mining), were chosen as the subjects of analysis.
Procedure: We compute the scores an each of the fourty test items every one of the occupational groups and find the equation of the regression line of scores of each agricultural, fishing, mining or white collar group (an aggregate of occupational groups such as professional and technical, managerial and afficial, clerical.)
Especially in agricultural and fishing groups, we compute the scores on each of the forty test items according to small schools (two classes and less) and large schools (6 classes and over in agricultural, 9 classes and over in fishing) and find the equation of the regression line of large school or small school.
Result: 12 equations of the regression line (95 per-cent confidence interval) found above is classfied into four types presented in table I-II.
