This article is the eighth in a series exploring the importance of research design, statistical analysis, and epidemiology in nutrition and dietetics research, and the second in a series focused on multivariate statistical analytical techniques. The purpose of this review is to examine the statistical technique, analysis of variance (ANOVA), from its simplest to multivariate applications. Many ...
this study was conducted to investigate the impact of portfolio assessment as a process-oriented assessment mechanism on iranian efl students’ english writing and its subskills of focus, elaboration, organization, conventions, and vocabulary. out of ninety juniors majoring in english literature and translation at the university of isfahan, sixty one of them who were at the same level of writing...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
ROC analysis is being used with greater frequency as an evaluation methodology in machine learning and pattern recognition. Researchers have used ANOVA to determine if the results from such analysis are statistically significant. Yet, in the medical decision making community, the prevailing method is LABMRMC. Although this latter method uses ANOVA, before doing so, it applies the Jackknife meth...
Hodges et al (2007) proposed smoothed analysis of variance (ANOVA) and showed how to use it to smooth interactions in balanced, single-error-term ANOVAs. Besides avoiding discontinuous choices to include or exclude effects, smoothed ANOVA addresses three practical concerns: unreplicated designs, masking in effects with many degrees of freedom, and “subgroup analysis”. The present paper extends ...
the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
