Preface
We designed this book as a semester textbook in biostatistics for students or researchers in the field of biology. We have also included resources that will be useful for physicians, public health professionals, and nurses who participate in research projects and want to not only understand the basic principles of biostatistics but also apply them in their research.
The number level was kept consciously. Our formulas and examples show how to calculate, which is crucial for understanding the results. We provide information about statistical programs that generate graphs and charts for research projects.
There are two types of units that serve the dual purpose of teaching basic principles and incorporating important tools for the effective execution of research projects. One type focuses on basic statistical techniques commonly used in biological and public health research. This includes a new section emphasizing the use of specific tests. Chapters 1 and 3 present the second type, which consists of elements useful for conducting research projects. In Chapter 1, we will present the first steps in designing a biological survey and describe common types of biological surveys. Chapter 3 is a new chapter that was not included in the previous book. It provides the first steps in planning a biological or public health study, including choosing what data to collect, how to collect it, and how to test data collection methods. It also provides a brief introduction to data entry and presentation. The remaining chapters focus on statistical techniques commonly used in biological and public health research.
You will find a short list of references at the end of each chapter. The trick here is to include at least one link containing the content mentioned in the title, as well as links containing additional information.
For the teacher interested in covering a text over a semester or quarter, please note that the chapters are short. We can summarize explanations for tests where population differences are known, and ignore the use of confidence limits for differences between two means. Neither function is available in most computer programs. The survival analysis major may not be as useful to public health students as it is to medical researchers. The fourth edition benefited from the work of Amy Hendrickson (TeXnology.com) in the proofreading and editing of the first chapters and the final edition of the book.I am sorry to inform you that Jean Dunn passed away in January 2008. I still love his book because he wrote the first two essays, and his clarity and writing make this a worthy choice for interested readers. Understand
