statistical methods in biological research

Biological research involves living organisms either manipulated in vitro or as wild types observed in nature. They are highly variable within a sample population. The study of statistics enables researchers to look at a large set of data and condense it into meaningful information. Both are important for gaining different kinds of knowledge. When working in fields such as science or medicine, trials are needed, and experimental data has to be collected and analyzed. The utilization of mathematical and statistical methods and tools are warranted to have a predictable extrapolation of the sample observations to the total population. The SC considered the distinction between the concepts of biological relevance and statistical significance and produced descriptions of the terms. Abstract : It is comparatively rare for a biologist to achieve eminence as a statistician in his own right.
