Research ArticleOpen accessEvery word in the titleAn Integrative Model for the Study of Attitudes Towards Statistics, Part 1: Establishing the Conceptual ModelMatus Ericka, Matus Lorena, Rodríguez Lucas, de Tristán SvetlanaWe propose a model to study attitudes towardsstatistics in higher education teachers. In the literature, there is a host ofscientific articles aimed at developing and applying measurement instrumentswhose psychometric characteristics are generally statistically acceptable.However, publications on the structure of attitudes and their relationship withteaching are relatively scarce-especially those dedicated to statistics inhigher education. Based on the system of attitudes proposed … …Journal of Social Sciences, Vol. 18, Issue 1 · 19 Sep 2022 · 5,898 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStatistical Demonstration of Superiority of High-Frequency Short-Tests in Assessment When Teaching Statistics to Enhance Higher Student Pass RatesSolly Matshonisa Seeletse, Tshepo Matsose, Gezani Richman Miyambu, Eunice Lebogang SesaleWhen facilitating learning, quick and small assessments can assist to detect areas that require further reinforcement and also identify students who need extra help in understanding the concepts taught. This paper demonstrates with Statistics, a difficult subject to pass at Higher Education Institution (HEI) level, that when these tests are administered at high frequencies and in large numbers, students are … …American Journal of Applied Sciences, Vol. 14, Issue 9 · 5 Oct 2017 · 7,155 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Robust Statistics, Exploring Document Analysis and Gis for Defining and Localizing Geochemical Anomalies-Case Study in Sin Quyen Copper Mine, Lao Cai Province, Viet NamQuoc Lap Kieu, Huu Tap VanApplication of robust statistic and Exploratory Data Analysis (EDA) as well as the support of Geography Information System (GIS) for defining and assessing geochemical anomalies. The research was conducted in Sin Quyen copper mine, Lao Cai province, Viet Nam with 1,284 combination of aquatic sedimentary geochemical sample in scale of 1/200,000. The area of 5,717.8 km2 was chosen to make … …Current Research in Geoscience, Vol. 7, Issue 2 · 1 Aug 2017 · 8,404 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleON THE PRODUCT AND RATIO OF TWO GENERALIZED ORDER STATISTICS FROM THE GENERALIZED BURR TYPE-II DISTRIBUTIONMohamed MaswadahIn this study, the probability density functions of the product and quotient of two generalized order statistics from the generalized Burr Type-XII distribution have been derived, using the Mellin transform and its inverse. Several interesting special cases have also been obtained such as the product and quotient of extreme generalized order statistics and the product and quotient of consecutive generalized … …Journal of Mathematics and Statistics, Vol. 9, Issue 2 · 10 May 2013 · 6,889 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleORDER STATISTICS FROM INDEPENDENT NON-IDENTICALLY DISTRIBUTED DISCRETE RAYLEIGH DISTRIBUTIONAmna Abdullatif JamjoomThis study deals with the subject of Order Statistics (OS) and its moments for independent non-identically distributed discrete random variables rv’s drawn from one parameter discrete Rayleigh distribution or dRayleigh (θ). Distributions of single order statistics and their moments for dRayleigh (θ) are studied. The kth moments of single os and the mean of the largest and smallest os are … …Journal of Mathematics and Statistics, Vol. 9, Issue 2 · 23 Apr 2013 · 7,051 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMOMENTS OF NONIDENTICAL ORDER STATISTICS FROM BURR XII DISTRIBUTION WITH GAMMA AND NORMAL OUTLIERSZ.A. Al-Saiary, A. A. JamjoomThere are some distributions with no simple closed form for distribution functions such as the Normal and Gamma distributions. This will be the problem if we want to find moments of nonidentical order statistics in the presence of Gamma and Normal outliers observations. We used the idea of approximating Normal and Gamma distributions with Burr type XII distribution. We get … …Journal of Mathematics and Statistics, Vol. 9, Issue 1 · 12 Apr 2013 · 7,040 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMoments of Order Statistics from Nonidentically Distributed Three Parameters Beta typeI and Erlang Truncated Exponential VariablesA. A. Jamjoom, Z. A. AL-SaiaryProblem statement: Moments of order statistics of independent non-identically distributed (INID) random variables is not an easy subject to deal with for continuous distributions. One is forced to use messy algebraic calculations (whether one uses permanents or not). This was the motivation behind this study. In this study the moments of order statistics arising from independent nonidentically distributed three parameters … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 31 Dec 2010 · 7,373 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTowards a Theory and View of Teaching Compressed and Abbreviated Research Methodology and Statistics CoursesJames Carifio, Lisa EriksonOne of the highly questionable effects of educational reform and other curriculum reshaping factors at both the high school, post-secondary and graduate levels has been the shift to teaching compressed, pared-down or abbreviated courses in still needed or required subject-matter that became de-emphasized in the current educational reformation. Research methodology, particularly the highly quantitative and experimental kind and statistics, are … …Journal of Social Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,760 accessesView PDFCite
