摘要：体育学研究16-5において農村児童の体格の発育状況を成分空間によって考察し, その方法的根拠を示したが, 今回は, 同様方法原理を用い因子空間によって地域差, 学年差を同一空間にて考察し, 横断的資料によるものであるが発育発達の地域差の分析を行った. 両地域児童の全学年資料を体格, 身体機能, 運動能力の3領域に分類し, 各領域毎に性別に全資料をプールして相関行列を求め, これに主因子解法を適用して, 全分散に対する貢献度が最大と第2番目に大なる因子を抽出し, 正規べリマックス法にて廻転して両因子を解釈し,この廻転後の2因子を直文軸とする因子平面を作り,この平面における地域別, 学年別の因子値の集合と平均値の大きさ, 位置関係を考察することから発育発達の検討を行った. この方法論は測定項目から能力を因子の形で抽出し, その能力値を因子値であらわして能力の発育発達を考察しようとするものである。
其他摘要：In the preceding paper, Research Journal of Physical Education 16-5, physical growth of rural school pupils was studied in the two dimensional component space. In this paper, the physical and motor development of elementary school children was investigated in the factor space, taking account of the differences in their residencial district and age (grade). The measures were divided into three categories; physique, organic function, and motor ability. The correlation matrix was computed with the pooled data of all grades in rural and urban schools in each variable category for each sex. The principal factor solution was applied to each correlation matrix, and the two factors corresponding to the largest and the second large eigenvalue were picked out and rotated in order to be interpreted. The factor space was constructed with these orthogonal factor axes. Then, the centroids and variance covariance matrices of grade-district groups were computed, and the 95% probability ellipses were computed and drawn in this factor space for each grade-district group. Actually, the motor ability can not be observed directly. Only one or a few test items were very often used to measure a certain sub-area of motor ability. As far as the motor ability is measured with performance test, it is more reasonable to think that several sorts of sub-area of motor ability contribute to such motor performance. Therefore, in order to measure a certain sub-area of motor ability, several test items which are validated in some way should be administered and the test result should be integrated to estimate such motor ability in some way. This seems to secure the greater degree of validity to measure the ability. This hypothesis led to the factor as the measure of sub-area of motor ability. Under this working hypothesis, the growth and development of physique, organic function and motor ability were investigated in the factor space as the ability space but not in the variable space.
