The Positive Interests Toward the Sea of Mercantile Marine Students in Indonesia-I : Methodological Examination about the Results of the Image Surveys

Abstract

Methodological examination was made about the results of image surveys by SD (semantic differential) method concerning homogeneity of items and groups. The neutral category of "neither" was examined whether its observed frequency was larger than the expected, obtained by fitting logistic curve on cumulative frequencies. As to groups, three parameters or moments of their distributions, variance, skewness and kurtosis, were calculated to compare response patterns. The Indonesian samples showed almost the same factor structure as those of Japan after procrustes rotation.
