Abstract
Clinical trials are for testing possible differences between new and standard treatment (or placebo). Statistical power is the chance of finding difference where there is one, and is thus very relevant, because it assesses thé underlying hypothesis of most research. Biostatistics is at the interface of mats and biology. Biostatistics is based on approximations rather than exactnesses(e.g. normal distributions, linear relation etc).
