The focus of this study was to identify the curricular preparation needs for sport club managers and to determine if there are differences in the curricular preparation needs for sport club managers in regard to organizational size. A questionnaire comprised of 30 curricular need statements was mailed to 500 randomly selected sport club managers; 264 responded. There were 83 in Group I, 95 in Group II, and 86 in Group III. A one-way analysis of variance test was employed for hypothesis testing. Tukey’s ω method was utilized for group comparison of rejected hypotheses, and factor analysis was employed for clustering of the curricular preparation needs. Marketing was the top rated curricular need. Two curricular need statements rejected were “program planning for youths” and “research interpretation and utilization,” and five clusters were extracted from factor analysis. Based on the findings of this study, curricular preparation needs for sport club managers have been identified; however, there seems to be little difference in curricular preparation needs in regard to organizational size.

The focus of this study was to identify the competencies needed to manage athletic clubs and to determine if differences exist in required competencies regarding organizational size. A random sample of 264 managers participated in the study; there were 83 in Group I, 95 in Group II, and 86 in Group III. A one-way analysis of variance was employed for hypothesis testing, Tukey’s ω method was utilized for comparing rejected hypotheses, and factor analysis was used for clustering competency areas. Based on the findings of this study, manager competencies have been identified and a difference does exist in managing varying sizes of athletic clubs.

The focus of this study aims to determine the effect of shuttle run, and zig-zag run training and self-confidence on passing productivity in Futsal players Pumata FC Tanjungbalai trying to improve athlete achievement among teenagers. This study uses an experimental research method by level 2 x 2, so the hypothesis submission is carried out using a two-way analysis of variance (ANAVA). After that, hypothesis testing was carried out using a two-way analysis of variance (ANAVA). This research was carried out at the PUMATA FC Team's training ground which was located at the Tanjungbalai city futsal field. The implementation time is about four weeks, with meetings three times a week. The sample of this research is all Pumata FC players consisting of 20 people who are given shuttle run training and zig-zag run training. Based on the analysis results above, it shows that there are differences in mean in the four groups by giving shuttle run and zig-zag run exercises. The highest mean value was obtained in the high self-confidence group trained with the zig-zag run, which was 8.60 (if rounded up to 9 successful passes). Meanwhile, the lowest mean value was obtained in the low self-confidence group trained with the shuttle run, which was 6.20 (if rounded up to 6 successful passes).

SummaryThis paper provides estimation and hypothesis testing procedures for experiments in split-plot designs. These experiments have been shown to have a convenient orthogonal block structure when properly randomized. Due to this property, the analysis of experimental data can be carried out in a relatively simple manner. Relevant simplification procedures are indicated. According to the adopted approach, the analysis of variance and hypothesis testing procedures can be performed directly, rather than by combining the results of analyses based on some stratum submodels. The practical application of the presented theory is illustrated by examples of real experiments in appropriate split-plot designs. The present paper is the fourth in the planned series of publications on the analysis of experiments with orthogonal block structure.

E-retailing has emerged as a significant player in the retail industry in India. The major cutthroat competition happens between Flipkart, Amazon, and Snap deal. These merchants have a significant competitive edge on electronic goods over other merchants in Indian online shopping portals. Thus, the purpose of this paper is to understand and analyses the universal perception and satisfaction quotient of customers in India concerning to the purchase of electronic goods via these e-commerce merchants.  We have used hypothesis testing and analysis of variance to understand customer satisfaction and customer perception. The results show that overall customer satisfaction is the highest for Flipkart. Also, the physical appeal and the quality of the product are the main reasons which impact the customer's perception toward not shopping online. This study is original in itself because it is limited to the purchase of electronic goods only from the emerging e-retail merchants-  Flipkart, Snap deal, and Amazon in India.

Data obtained from the Personal Beliefs Scale of Embree and Embree were used to develop an analysis of variance model for mind-body belief which emphasized a distinction between “conventional” and “unconventional” mind-body beliefs. By means of this model a critically important distinction between high scoring second-order psychosomaticism subjects was achieved. It was proposed that subjects low in unconventional/high conventional tend to employ classical logic when rating mind-body belief items and that subjects high in unconventional/high conventional mind-body belief characteristically engage in fuzzy logic. Possible applications of the model in research were discussed.
