Description
New Age International (P) Ltd., Publishers A Textbook Of Biostatistics by Dr. B. Annadurai
My goal in writing this book was to generate an accessible and relatively complete introduction of the use of statistics in the biological sciences.
This text emphasizes the relationships among probability, probability distributions and hypothesis testing. The expected value of various test statistics under the null and research hypotheses has been highlighted as a way to understand the methodology of hypothesis testing. In addition, nonparametric alternatives to many situations along with the standard parametric analysis are incorporated. These nonparametric techniques are included because PG student projects often have small sample sizes that preclude parametric analysis and because the development of the nonparametric tests is usually readily understandable for students with modest math backgrounds. The nonparametrics can be skipped or skimmed without any loss of continuity.
I have tried to include interesting and easily understandable examples with concept. The problems at the end of each chapter have a range of difficulty and come from a variety of disciplines. Most are not real life examples but are realistic in their design and data values. The end-of-chapter problems are randomized within each chapter to require the student to choose the appropriate analysis. This approach prevents students from having to make the real life decision about the appropriate analysis. I believe this decision- making is a critical skill in the statistical analysis and have provided a large number of opportunities to practice and develop this skill.
