The yield was measured after the harvest. Because the 3 rd method was not tested on the 4 th type of field (because of a lack of seeds), and the 2 nd method on the 4 th type of field (because of a hail storm), the experiment is a typical example of an unbalanced ANOVA. We have performed an ANOVA with interactions in order to determine the interactions between the types of methods used and the t...

We consider inferences in a one-way ANOVA model with equicorrelation error structures. Hypotheses of the equality of the means are discussed. A generalized F-test has been proposed by in the literature to compare the means of all populations. However, they did not discuss the performance of that test. We propose two methods, a generalized pivotal quantities-based method and a parametric bootstr...

Analysis of variance (ANOVA) is one of the most frequently used statistical methods in medical research. The need for ANOVA arises from the error of alpha level inflation, which increases Type 1 error probability (false positive) and is caused by multiple comparisons. ANOVA uses the statistic F, which is the ratio of between and within group variances. The main interest of analysis is focused o...

perceptual-motor skills play a vital role in many tasks of daily life and sports skills. the measurement of coincidence anticipation timing ability is a method to evaluate perceptual and perceptual-motor skills. thus, the main aim of the present study was to investigate the role of different organism, task and environment constraints in coincidence anticipation timing accuracy. for this purpose...

PURPOSE This preliminary study aimed to determine the intrarater reliability of the quantitative tests for the study of non-specific low back pain. METHODS Test-retest reliability of the measurements of ratio data was determined by an intraclass correlation coefficient (ICC), standard error of measurements (SEMs), coefficient of variation (CV), and one-way repeated measures ANOVA using the va...

the present study aimed to examine throwing accuracy and spatial and digit working memory of field dependent-independent participants. the group embedded figure test (geft) was distributed among 320 male students and based on the geft scores, 45 participants were randomly divided into field dependent, field independent and control group (15 participants/each group). the study included two tasks...

The analysis of change is central to the study of kidney research. In the past 25 years, newer and more sophisticated methods for the analysis of change have been developed; however, as of yet these newer methods are underutilized in the field of kidney research. Repeated measures ANOVA is the traditional model that is easy to understand and simpler to interpret, but it may not be valid in comp...

  Objective: Tooth surface undergoes continuous remineralization and demineralization. The aim of this study was to compare the effect of Caseinphosphopeptide-amorphous calcium phosphate (CPP-ACP) paste and Fluoride gel on the microhardness of demineralized enamel lesions.   Methods: Frothy eight specimens of premolar teeth were chosen and randomly divided to 4 groups of 12. After the initial m...
