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

Love these!
Size: Standard (20" X 26"), Color: 02 - White - Zipper, Number of Items: 2
I like these better than the Blissy mulberry silk pillowcase. They feel smoother and softer and make my hair less frizzy. I've been buying these for years and they hold up great! I just switched to the zipper version instead of the envelope style, and I really like the more modern aesthetic of the hidden zipper. They are nice!

Nice pillow cases, good construction and materials. But just a little short length wise. Very tight fit

I bought these because they were recommended by my hairdresser for hair breakage. I love the zipper because the pillow can’t slip out. I will sy these do feel nice against the skin as well.

Feels heavenly
Size: King (20" X 36"), Color: 14 - Lavender - Zipper, Number of Items: 2
Literally just got it in the mail and fell in love. It's so soft and wasn't being harsh with my beard hair. Hopefully no more split ends! (Good hair protection!)
There was no odor to speak of and it fit my pillow perfectly, we got king size, (AKA good compatibility)
