On numerous occasions, researchers in a wide variety of subject areas, have asked how do I carry out a particular statistical test? The answer often involved programming complicated formulas into spreadsheets and looking up test statistics in tabulations of probability distributions. With the rise of R, statistical testing is now easier than ever. 100 Statistical Tests in R is designed to give you rapid access to one hundred of the most popular statistical tests. It shows you, step by step, how to carry out these tests in the free and popular R statistical package. Compared to other books, it has:
- Breadth rather than depth. It is a guidebook, not a cookbook.
- Words rather than math. It has few equations.
- Illustrations and examples rather than recipes and formulas.
Who is it for?
100 Statistical Tests in R, as with all books in the Easy R series, came out of the desire to put statistical tools in the hands of the practitioner. The material is therefore designed to be used by the applied researcher whose primary focus is on their subject matter rather than mathematical lemmas or statistical theory. Examples of each test are clearly described and can be typed directly into R as printed on the page. To accelerate your research ideas, over three hundred published applications of statistical tests across engineering, science, and the social sciences are contained in these pages. These illustrative applications cover a vast range of disciplines incorporating numerous diverse topics such as the angular analysis of tree roots, Angelman syndrome, breastfeeding at baby friendly hospitals, comparing cardiovascular interventions, computing in those over 50, dog- human communication, effects of t’ai chi on balance, environmental forensics, the randomness of the universe, emotional speech, the solar orientation of sandhoppers, horses concept of people, hematopoietic stem cell transplantation, idiopathic clubfoot in Sweden, prudent sperm use, men’s artistic gymnastics, software defects, stalagmite lamina chronologies, sexual conflict in insects, South London house prices, Texas hold’em poker, vampire calls, and more! Comprehensive references are given at the end of each test. In keeping with the Zeitgeist of R, copies of all of the papers discussed in this text are available for are free.
