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

Color is not the same as picture, too light, assembly is harder than it should be
Size: g:Square Table with Umbrella Hole, Color: Light Grey
I had higher hopes for this table given the 80 dollar price tag. The gray finish is MUCH brighter than what is displayed in the picture. What's advertised matched the gray Adirondack set that I currently have in my yard, what came in was about 5 shades lighter. The assembly only had a few steps to it with a total of 8 bolts but it was more difficult that it had to be has the holes didn't line up very well and I actually had to bend one of the metal pieces to get the screw to line up. I ordered this piece initially to serve two purposes, the first was to add more stability to my ever blowing over umbrella, the second was to add a matching table piece in-between my two Adirondack chairs. This piece does neither very well. It is too light in color to match and serve to complete the set, and it is not heavy enough to add any layer of stability. For these reasons, I cannot recommend this piece.

Nice, but...
Size: g:Square Table with Umbrella Hole, Color: Black
Second one I bought. So I do like it, but for the price they could include an extra screw and washer. Also it would be much more convenient if the holes would line up correctly. That's why I gave only 3 stars. But it is a nice table.

Durability
I was very satisfied with the quality of another Best Choice Products: Ice Chest. So, I was happy to see the umbrella stand, weighted by water, was available by this company. It is, once again, made very resilient and strong to withstand tipping over. I'm a happy customer of this company's products!

Great design and easy to put together!
Color: Black - Square
Works very well and this is easily put together!
I filled mine with water and it is more than heavy enough to withstand a strong gust of wind. Highly recommended!
