It introduces SPSS functionality and shows how to segregate data, draw random samples, file split, and create variables automatically. It then goes on to cover different assumptions required in survey studies, and the importance of designing surveys in reporting the efficient findings. The book provides various parametric tests and the related assumptions and shows the procedures for testing these assumptions using SPSS software. To motivate readers to use assumptions, it includes many situations where violation of assumptions affects the findings. Assumptions required for different non-parametric tests such as Chi-square, Mann-Whitney, Kruskal Wallis, and Wilcoxon signed-rank test are also discussed. Finally, it looks at assumptions in non-parametric correlations, such as bi-serial correlation, tetrachoric correlation, and phi coefficient.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAn excellent reference for graduate students and research scholars of any discipline in testing assumptions of statistical tests before using them in their research study\u003c\/li\u003e \u003cli\u003eShows readers the adverse effect of violating the assumptions on findings by means of various illustrations\u003c\/li\u003e \u003cli\u003eDescribes different assumptions associated with different statistical tests commonly used by research scholars\u003c\/li\u003e \u003cli\u003eContains examples using SPSS, which helps facilitate readers to understand the procedure involved in testing assumptions\u003c\/li\u003e \u003cli\u003eLooks at commonly used assumptions in statistical tests, such as z, t and F tests, ANOVA, correlation, and regression analysis\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003ci\u003eTesting Statistical Assumptions in Research\u003c\/i\u003e is a valuable resource for graduate students of any discipline who write thesis or dissertation for empirical studies in their course works, as well as for data analysts.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e J.
