| mann whitney test assumptions: Nonparametric Statistics for Non-Statisticians Gregory W. Corder, Dale I. Foreman, 2011-09-20 A practical and understandable approach to nonparametric statistics for researchers across diverse areas of study As the importance of nonparametric methods in modern statistics continues to grow, these techniques are being increasingly applied to experimental designs across various fields of study. However, researchers are not always properly equipped with the knowledge to correctly apply these methods. Nonparametric Statistics for Non-Statisticians: A Step-by-Step Approach fills a void in the current literature by addressing nonparametric statistics in a manner that is easily accessible for readers with a background in the social, behavioral, biological, and physical sciences. Each chapter follows the same comprehensive format, beginning with a general introduction to the particular topic and a list of main learning objectives. A nonparametric procedure is then presented and accompanied by context-based examples that are outlined in a step-by-step fashion. Next, SPSS® screen captures are used to demonstrate how to perform and recognize the steps in the various procedures. Finally, the authors identify and briefly describe actual examples of corresponding nonparametric tests from diverse fields. Using this organized structure, the book outlines essential skills for the application of nonparametric statistical methods, including how to: Test data for normality and randomness Use the Wilcoxon signed rank test to compare two related samples Apply the Mann-Whitney U test to compare two unrelated samples Compare more than two related samples using the Friedman test Employ the Kruskal-Wallis H test to compare more than two unrelated samples Compare variables of ordinal or dichotomous scales Test for nominal scale data A detailed appendix provides guidance on inputting and analyzing the presented data using SPSS®, and supplemental tables of critical values are provided. In addition, the book's FTP site houses supplemental data sets and solutions for further practice.

Parke's Essential First Steps to Data Analysis: Scenario-Based Examples Using SPSS provides instruction and guidance on preparing quantitative data sets prior to answering a study's research questions. Such preparation may involve data management and manipulation tasks, data organization, structural changes to the data files, or conducting preliminary analysis. Twelve research-based scenarios are used to present the content. Each scenario tells the story of a researcher who thoroughly examined their data and the decisions they made along the way. The scenario begins with a description of the researcher's study and his/her data file(s), then describes the issues the researcher must address, explains why they are important, shows how SPSS was used to address the issues and prepare data, and shares the researcher's reflections and any additional decision-making. Finally, each scenario ends with the researcher's written summary of the procedures and outcomes from the initial data preparation or analysis. |

| mann whitney test assumptions: Multivariate Nonparametric Methods with R Hannu Oja, 2010-03-25 This book offers a new, fairly efficient, and robust alternative to analyzing multivariate data. The analysis of data based on multivariate spatial signs and ranks proceeds very much as does a traditional multivariate analysis relying on the assumption of multivariate normality; the regular L2 norm is just replaced by different L1 norms, observation vectors are replaced by spatial signs and ranks, and so on. A unified methodology starting with the simple one-sample multivariate location problem and proceeding to the general multivariate multiple linear regression case is presented. Companion estimates and tests for scatter matrices are considered as well. The R package MNM is available for computation of the procedures. This monograph provides an up-to-date overview of the theory of multivariate nonparametric methods based on spatial signs and ranks. The classical book by Puri and Sen (1971) uses marginal signs and ranks and different type of L1 norm. The book may serve as a textbook and a general reference for the latest developments in the area. Readers are assumed to have a good knowledge of basic statistical theory as well as matrix theory. Hannu Oja is an academy professor and a professor in biometry in the University of Tampere. He has authored and coauthored numerous research articles in multivariate nonparametrical and robust methods as well as in biostatistics. |

| mann whitney test assumptions: Research Methodology And Applied Statistics Dr. Rajib Mallik, Dr. Archana Kumari Prasad, Professor Swati Prakash Raut, Dr. Pranjit Kumar Bhuyan, Methodology in research refers to a set of guidelines for designing and carrying out a study. The methodology! is a broad phrase that may refer to several different aspects of a study's execution, including but not limited to its planning, execution, and analysis. The goal of research methodology is to provide answers to a wide range of questions about a research problem or study, such as: why the study was conducted; how the research problem was defined; how and why the hypothesis was formulated; what data were gathered; what method was used to analyze the data; and so on. A researcher will! use a research technique to explain how and why they are doing their study. Study methodology provides the proper setting for the researcher to plot out the study project in context and create sound preparations at the appropriate moment. Moreover, the research technique encourages the researcher to participate actively in the study of his or her chosen topic. In most cases, the study subject and the research purpose will be different from one another, but this may be overcome by using an appropriate approach. In contrast to research methods, which are the particular procedures and instruments used for collecting, analyzing, and interpreting data, research methodology refers to the overarching plan or approach used in conducting a study. |
