It is not intended to be a text for a complete statistics course – only a guide to few relatively simple tests . Complex hypothesis testing procedures are not covered. For example, the discussion of Analysis of Variance (ANOVA) introduces what is called one way ANOVA. Two way ANOVA, a more complex procedure involving the use of blocking variables, is not covered. It simply presents a few commonly used tests and down-to-earth explanations of how to use them.
It is intended to be a low cost supplement that can help its reader understand a few commonly-used tests. It was put together on a shoestring by a non-mathematician for the benefit of other non-mathematicians -- or for mathematicians who have forgotten some or all of the statistics they have studied. There are no color illustrations or professionally-prepared charts and graphs. Economy was a guiding principle.
Four brief introductory chapters discuss numbers, basic terms, measures of central tendency and dispersion, probability, and data presentation. With that background the book then introduces various tests and explains them in down to earth language.

Dr. G. is a retired university professor. He supervised graduate level
research projects for more than twenty years and found that students
often encountered frustration and project delay because they lacked
understanding of the basics of hypothesis testing. These students needed
tutorial help to pick and choose among various types of simple tests
they could apply to their research data and then could proceed
successfully. Developing a formal course to prepare students for
research projects, he determined to include in that course an
introduction to hypothesis testing that would give students practical
help - brief lectures, practice problems, and problem solutions for
discussion. His book is a direct result of that practical experience.
It is intended to be an easy to understand tutorial that will help the
student researcher develop and test a hypothesis meaningful to his or
her research objective.
