Medical Statistics

Medical statistics are important for assessing the usefulness, or value of some particular treatment or alternatively considering factors which can cause or aggravate disease conditions.

As clinical trials are expensive, and there is a cost associated with each patient-treatement it is important to understand the required power of a test, in order to select the correct number of treatment "units"

When outcome differences are small, or incidence is a tiny percentage, statistics techniques are required to tease out significant results from large datasets produced over long time periods.
