The purpose of this study was to investigate item goodness-of-fit of Scale, Rasch rating scale model was applied to 4 dimensions 12 items of the Core Self-Evaluations Scale(CSES) in a sample of College player(n=522). An assumption to test Rasch Model, which is satisfaction of unidimensionality, is regarded through PCAR test, and WINSTEPS 3.65 program is used to test the goodness-of-fit of items. The results of this study were: First, 3-point rating category was appropriate for the CESES instead of the existing 5-point rating category. Second, as a result of analyzing the goodness-of-fit of the items, 9 items of the CSES were suitable, but 3 items were not. Third, the item reliability of person separation and the person reliability of item separation of the CSES was acceptable. Fourth, as a result of comparing the individual attribute score and the difficulty level through the Item-Person Map, the distribution of the individual attribute and item difficulty distribution was shown to be appropriated.

The subjects of this study were 250 middle school students in Seoul and distributed and collected the questionnaires. Of the collected questionnaires, 228 were used for the actual analysis, except for double - entry and a series of responses.

Third, the physical education attitude of middle school students partially affects the of the continuous sports participation. In other words, the basic attitude, which is a sub - factor of physical education class attitude, affects behavioral participation and social attitude affects behavioral participation and cognitive participation.

The classical frequentist inference method has a disadvantage in that there is no prior distribution, and it can only make very limited inferences due to the viewpoint that the parameter of interest is regarded as an unknown and fixed constant. This disadvantage is that when the number of cases increases, it is easy to reject the null hypothesis, so that an insignificant variable is sometimes interpreted as an important variable. In addition, hypothesis testing centered on the null hypothesis makes it difficult to compare the two hypotheses by excluding the evaluation based on the relative hypothesis. This problem is a common phenomenon in the field of physical education, and it can be said that an appropriate reasoning method is needed for it. Recently, the Bayesian reasoning method is used to estimate parameters and test hypotheses in various academic fields as a method to solve the shortcomings of the classical frequentist reasoning method, but it can be said that the frequency of use in studies in the field of physical education is extremely insignificant. This problem is thought to have been largely due to the lack of understanding and ignorance of the Bayesian reasoning method in physical education research. Therefore, in this study, we intend to discuss the effectiveness of the Bayesian reasoning method by increasing the understanding of the Bayesian reasoning method of physical education researchers and further analyzing and comparing it by applying actual data.

베이지안 위계적 모델을 적용한 KBL 선수들의 포지션과 3점슛 능력의 관계 분석

허종관(Heo, Chong-Kwan),정철규(Jung, Chul-Kyu) 한국체육과학회 2023 한국체육과학회지 Vol.32 No.6

This study aims to identify differences in 3-point shooting ability depending on position by confirming the structural relationship between the position and 3-point shooting ability of Korean professional basketball players. For this purpose, game results related to 3-point shots of professional basketball players from 2021 to 2022 were collected from the KBL website, and the collected results were analyzed by applying a Bayesian hierarchical model. the results are as follow: 1. the position with the highest 3-point shooting ability was guard, followed by forward and center. The group with the highest heterogeneity was the center. 2. there was no significant difference in the 3-point shooting ability between guard-forward, guard-center, and forward-center at the 95% HDI level. 3. as a result of verifying the difference by extracting one player from each position with relatively high 3-point shooting ability, it was found that there was no significant difference at the 95% HDI level. Therefore, it can be concluded that there is currently no difference in 3-point shooting ability depending on position in Korean professional basketball, and these results suggest that there is a change in role depending on position in domestic professional basketball games.

The goal of this study is in estimating the causal relationship among leisure identity salience (LIS), negotiation efficacy (NE), leisure constraints negotiation (LCN), and intentions to participate in leisure activity (IPLA). For this, we estimated their structural models using data collected from 296 college male and female students residing in Seoul and Gyong-gi providence and could obtain consequences as follows. First, for both male and female students, NE increased as LIS increased, and this affected positive impacts on LCN and IPLA, so that LIS and NE played significant roles in the process of LCN. Second, for male students. LIS turned out to affect LCN more significantly than female students in the sense of statistics, so that LIS was a statistically significant variable in the process of LCN. Third, on the other hand, the mediatory roles of LIS and NE were more important for female students in the process of LCN than male students. In addition, relative magnitude of LCN was more important to IPLA for female students, too.
