What Is A Powered Study. What are power and sample size calculations? Choosing an appropriate size for an experimental study is one major component in the design of any research study. The statistical power of a study is the power, or ability, of a study to detect a difference if a difference really exists. Statistical power is a measure of study efficiency, calculated before conducting the study to estimate the chance of discovering a true effect rather than obtaining a false negative. In the paper you link, they seem to be using the term unpowered to mean the study was not designed with power in mind (that is,. Power analysis is the process of calculating the statistical power of a study and determining what size sample you need to. Statistical power, or sensitivity, is the likelihood of a significance test detecting an effect when there actually is one. Statistical power, also called sensitivity, indicates the probability that a study can distinguish an actual effect from a chance occurrence.
