Download or read book The Wilcoxon Mann Whitney Test an Introduction to Nonparametrics written by Frederick Ruland and published by . This book was released on 2018-10-16 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most introductory statistics books there is a chapter in the back that deals with a few nonparametric tests. Perhaps two pages are devoted to the Wilcoxon-Mann-Whitney Test (or its equivalent the Mann-Whitney U Test). The Wilcoxon-Mann-Whitney Test addresses a specific niche involving two groups of relatively small sample size. Some may disagree with this niche characterization, but with qualifications, I believe it to be true. One of the strengths of this test is in small scale experimental testing. Small scale, in this context, refers to the number of observations. Examples might include test crashing new automobiles, medical studies of rare diseases, and small pilot studies; in effect, any situation where resources of one kind or another limit the number of observations. An advantage of the Wilcoxon-Mann-Whitney Test is that you don't need to accept or confirm many of the assumptions required by other approaches. The measurements only need to be on an ordinal scale, as opposed to requiring ratio or interval level measurements.The book covers the mechanics of doing the test. The strengths and weaknesses are discussed, and the use of different style probability tables is explained. Perhaps on a more practical note, the book discusses the R procedure 'wilcox.test' and reviews some of its options. (The book also shows how to invent a 'desert island' version of the test - just in case.)In learning different statistical tests, it helps to get a good hold on at least one. After that, you have a reference to compare with other procedures. The Wilcoxon-Mann-Whitney Test - which can be conducted on the proverbial table napkin - can provide an introduction to a whole family of useful tests.

Download or read book A Gentle Introduction to Stata Second Edition written by Alan C. Acock and published by Stata Press. This book was released on 2008-09-03 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A Gentle Introduction to Stata, Second Edition is aimed at new Stata users who want to become proficient in Stata. After reading this introductory text, new users will not only be able to use Stata well but also learn new aspects of Stata easily. Acock assumes that the user is not familiar with any statistical software. This assumption of a blank slate is central to the structure and contents of the book. Acock starts with the basics; for example, the portion of the book that deals with data management begins with a careful and detailed example of turning survey data on paper into a Stata-ready dataset on the computer. When explaining how to go about basic exploratory statistical procedures, Acock includes notes that should help the reader develop good work habits. This mixture of explaining good Stata habits and good statistical habits continues throughout the book. Acock is quite careful to teach the reader all aspects of using Stata. He covers data management, good work habits (including the use of basic do-files), basic exploratory statistics (including graphical displays), and analyses using the standard array of basic statistical tools (correlation, linear and logistic regression, and parametric and nonparametric tests of location and dispersion). Acock teaches Stata commands by using the menus and dialog boxes while still stressing the value of do-files. In this way, he ensures that all types of users can build good work habits. Each chapter has exercises that the motivated reader can use to reinforce the material. The tone of the book is friendly and conversational without ever being glib or condescending. Important asides and notes about terminology are set off in boxes, which makes the text easy to read without any convoluted twists or forward-referencing. Rather than splitting topics by their Stata implementation, Acock chose to arrange the topics as they would be in a basic statistics textbook; graphics and postestimation are woven into the material in a natural fashion. Real datasets, such as the General Social Surveys from 2002 and 2006, are used throughout the book. The focus of the book is especially helpful for those in psychology and the social sciences, because the presentation of basic statistical modeling is supplemented with discussions of effect sizes and standardized coefficients. Various selection criteria, such as semipartial correlations, are discussed for model selection. The second edition of the book has been updated to reflect new features in Stata 10 and includes a new chapter on the use of factor analysis to develop valid, reliable scale measures."--Publisher's website.

Download or read book Statistics for Health Care Professionals written by Ian Scott and published by SAGE. This book was released on 2005-01-13 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistics for Health Care Professionals is an accessible guide to understanding statistics within health care practice. Focusing on quantitative approaches to investigating problems, the book introduces the basic rules and principles of statistics. Challenging the notion that statistics are often incomprehensible and complex to use, the authors begin by presenting a `how to' section explaining how specific statistical tests can be performed. They also help readers to understand the language of statistics, which is often a stumbling block for those coming to the subject for the first time. The reader is taught how to calculate statistics by hand as well as being introduced to computer packages to make life easier, and then how to analyse these results. As the results of health care research are so integral to decision-making and developing new practice within the profession, the book encourages the reader to think critically about data analysis and research design, and how these can impact upon evidence based practice. This critical stance is also crucial in the assessment of the many reports and documents issued within the health industry. Statistics for Health Care Professionals includes practical examples of statistical techniques throughout, and the exercises within and at the end of each chapter help readers to learn and to develop proficiency. There is also a glossary at the end of the book for quick and easy referencing. This book is essential reading for those coming to statistics for the first time within a health care setting.
