Sample size calculation: Basic principles
Indian Journal of Anaesthesia, 2016 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 ...

Sample Size Calculations [PDF]
Nephron Clinical Practice, 2011 The sample size is the number of patients or other experimental units that need to be included in a study to answer the research question. Pre-study calculation of the sample size is important; if a sample size is too small, one will not be able to detect an effect, while a sample that is too large may be a waste of time and money. Methods to calculate
