Many universities, hospitals, and medical research facilities offer short courses in introductory biostatistics for the clinicians, fellows, nurses, and health practitioners to become familiarized with statistical methods. Written in a concise, clear, and straight-to-the-point style, this book begins with a basic introduction to the relationship between biostatistics and medical research. Subsequent chapters explore numerical techniques, including sampling from populations, graphics and summary statistics, normal distribution and related properties, estimating means and proportions, hypothesis testing, correlation, regression, diagnostics, logistic regression, contingency tables, nonparametric methods, and survival analysis.
