Addressing a sample size is a practical issue that has to be solved during planning and designing stage of the study. The aim of any clinical research is to detect the actual difference between two groups (power) and to provide an estimate of the difference with a reasonable accuracy (precision Cited by: 9. Abstract. One of the most common requests that statisticians get from investigators are sample size calculations or sample size justifications. The sample size is the number of patients or other experimental units included in a study, and determining the sample size required to answer the research question is one of the first steps in designing a by:

The book highlights statistical procedures for sample size calculation and justification that are commonly employed in clinical research and development. It provides clear, illustrated explanations of how the derived formulas and/or statistical procedures can be used/5(4).
The book has an academic flavor, however the intended audience is clinical trials practicioners. It would be much better to start each chapter with a couple of strong examples, then description of the methodology, and finally sample size calculations. I think this book needs a lot of improvement before it can be used as a good reference/5(4).
