Abstract
Sample-size determination is a crucial component of study design. Esti mates of sample size are influenced by the amount of change that must occur between study groups and the degree of risk that the investigato r is willing to accept in evaluating the null hypothesis. A complete u nderstanding of the impact of sample size on the interpretation of stu dy data is therefore a prerequisite for quality, innovative, valid res earch.
