A statistical test is developed based on the comparison of sums of squared errors associated with two competing models. A model based on cell means is compared to a representation that specifies the means for the treatment conditions. Comparing models is more general than the traditional H0 in analysis of variance wherein all the cell means are assumed equal. The test statistic, Proportional Increase in Error, is computed using the SAS statistical system.

AbstractFluid intelligence is a crucial cognitive ability that predicts key life outcomes across the lifespan. Strong empirical links exist between fluid intelligence and processing speed on the one hand, and white matter integrity and processing speed on the other. We propose a watershed model that integrates these three explanatory levels in a principled manner in a single statistical model, with processing speed and white matter figuring as intermediate endophenotypes. We fit this model in a large (N=555) adult lifespan cohort from the Cambridge Centre for Ageing and Neuroscience (Cam-CAN) using multiple measures of processing speed, white matter health and fluid intelligence. The model fit the data well, outperforming competing models and providing evidence for a many-to-one mapping between white matter integrity, processing speed and fluid intelligence. The model can be naturally extended to integrate other cognitive domains, endophenotypes and genotypes.

Kesimpulan dari penelitian ini dilihat dari hasil uji signifikan perbedaan peningkatan latihan kedua kelompok menunjukkan bahwa latihan acak memberikan pengaruh yang lebih signifikan terhadap hasil  penguasaan teknik dasar bola basket. Kata Kunci: Latihan terpusat, Latihan acak, Teknik Dasar Bola Basket.Abstract This study aims to determine the effect of centralized training and random exercise on the results of mastery of basic techniques of basketball. This study used experimental methods conducted on two groups, namely the experimental group one which was given the treatment of centralized exercise and the experimental group of two in the treatment of random treatment. The research was conducted at Club Basket Poltekkes Kemenkes Bengkulu with selected samples based on certain characteristics. The statistical analysis used in this study is t-test to test the hypothesis that "randomized exercise gives better effect than centralized training in improving basic basketball technique skills". Test statistic requirement t has complied with homogeneous requirements and normal distributed data based on statistical calculation and statistical test criterion test in can result that centralized exercise and random exercise have an effect on the result of mastery of basic technique of basketball. It is known from thitung = -5,11> ttable = 2,11 with ? = 0,05. The conclusions of this study seen from the results of significant test differences in the improvement of the two groups showed that the random exercise gives a more significant effect on the results of mastery of basic techniques of basketball. Keywords: Centralized exercise, Random exercise, Basic Basketball Technique.

Performance characteristics of leather and synthetic basketballs were examined by measuring the basketballs' rebound heights on five types of playing surfaces (Tartan, asphalt, glass, concrete, hardwood). Comparing the basketballs' performance on the basis of their coefficients of restitution (e = height of rebound/height of drop) analysis of variance showed that the leather basketball rebounded significantly higher than the synthetic basketball on all surfaces. To assess the capability of individuals to discriminate perceptually between the balls 30 male and 30 female undergraduates were asked to determine whether basketballs randomly presented 20 times under four different treatment conditions (visual, tactual-kinesthetic static, tactual-kinesthetic dynamic, auditory) were leather or synthetic. Chi squared analysis of their accuracy across all four perceptual modes showed no significant difference. However, analysis by perceptual mode did produce significant differences, indicating subjects were more accurate in identification in the tactual-kinesthetic dynamic and static modes than in the visual and auditory.

This study used the multivariate analysis of variance (MANOVA) test statistic to examine the impact of three categories feed used in the production of pig in Delta State. The multivariate test statistic considered are the Pillai – Bartlett trace, Wilks’ Test Statistic, Roy’s Largest Root Test Statistic, and the Lawley- Hotelling (LH) Statistic. The objectives include to: evaluate the robustness of the four Multivariate Analysis of Variance test statistics to ensure that the best is employed in multivariate analysis to guarantee most useful result in pig production; determine the relatively efficient test statistic for pig production; and determine the test statistic that is consistent across the sample sizes. Secondary source of data collection was used to obtain the data required for the analysis. The outcome of the study showed that the obtained data was multivariate normally distributed based on the result of the asymmetry-based multivariate normality test and the multivariate normality test based on the kurtosis test which makes the data suitable parametric multivariate method such as multivariate analysis of variance (MANOVA). The results show that the Wilks and Roy tests found a significant difference for the intercept. While the Pillai and LH tests could not find any significance. The Roy test was also found to be significant for feed one, feed two, and feed three. The Wilks and Roy tests also turned out to be significant differences for the intercept. All test measures showed significance for feed one. The Wilks and Roy tests also showed a significant difference for feed two, while all test measures found a significance for feed one. Another result showed that none of the tests found significance for the interaction between feed one and two, while the Roy test found significance for the interaction between feed one and three, feed two and three and feed one, two and three. The performance of the test for evaluating the performance of feeds for pig production with/without considering interactions was found to be in the following order of magnitude: Roy, Wilks and Pilla = LH. This result implies that the Roy method, with or without consideration of the interaction, has a better performance of the test than the other methods considered in the study.

Purpose The purpose of this paper is to analyse the levels of belief in importance of information literacy abilities (BILAs) among an undergraduates’ sample. The aim is, on the one hand, to discover if there is a representative latent structure and, on the other hand, to know the existing differences according to external variables such as academic degree, course, gender and age. Design/methodology/approach A self-assessment questionnaire (IL-HUMASS) was applied to a sample of 749 students in English Studies, Translation and Interpreting and Education in Spain. Three types of statistical methods have been used to study the results: descriptive, factorial and analysis of variance. Findings Students’ levels of BILAs are acceptable but improvable. A framework of six underlying factors has been uncovered: evaluation-ethics, searching-using, technological processing, communication, dissemination and cognitive processing of the information. Significant differences on degree, course and gender have been found. Practical implications This paper is intended for a broad academic sector, including faculty, librarians and students in higher education. The BILAs construct helps to improve the diagnosis of the perception of the BILAs. Its representation through a reduced number of latent factors simplifies results and possible applications. The results show that variations in degree, course and gender are significant and should be taken into account. Originality/value Although much has been written about information literacy abilities, we still know little about the importance students place on them. The BILAs construct is intended to improve that knowledge.

Paired rankings arise when each subject in a study independently ranks a set of items, undergoes a treatment, and afterwards ranks the same set of items. For such data, a statistical test is proposed to detect if the subjects’ posttreatment rankings have moved systematically toward some unknown ranking or set of rankings. The null hypothesis for this test is that each subject’s post-treatment ranking is symmetrically distributed about his pretreatment ranking. The exact and asymptotic null distributions of the test statistic are simulated and compared, and the power of the test is studied. Using paired rankings from an experimental course in literary criticism, we also offer some graphical methods for representing such data that help us to interpret the test results.
