Description:
Comprehensively teaches the basics of testing statistical assumptions in research and the importance in doing so
This book facilitates researchers in checking the assumptions of statistical tests used in their research by focusing on the importance of checking assumptions in using statistical methods, showing them how to check assumptions, and explaining what to do if assumptions are not met.
Testing Statistical Assumptions in Research discusses the concepts of hypothesis testing and statistical errors in detail, as well as the concepts of power, sample size, and effect size. 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.
An excellent reference for graduate students and research scholars of any discipline in testing assumptions of statistical tests before using them in their research study

Excellent quality
Size: Large, Color: Purple
Perfect tuxedo to use for many functions. Got it about 2 years ago and have used it probably twice for galas as well as awards programs. Fits to size and didn’t break the bank. Texture is good and it is easy to pair with anything as well as is reusable.

The suit is amazing!! I just hate it arrived 3 days before prom after being delayed twice. It fit my son great, the blue was exactly as shown. It was not wrinkled or funny smelling at all. The material was very good and it will last a while. My son is 5’11, 150lbs, size medium

Misleading
Size: Small, Color: Brown
This is a very horrible material and poorly made suit, I have never bought anything this bad in amazon before, the crazy thing is that I returned this thing to get a refund and they shipped back the exact same garbage back to me.
I clearly do not like anything about it, this is a misleading advert
