I would like to learn the limitations of statistics in different domains of biological research. How it affects the outcome, future perspectives of medicine in terms of diagnosis, treatment, and effect of causative agents.
"Does it make sense? will often cut a statistic down to size" - D Huff
Statistics is a 'play with numbers' in the sense that significance of a particular data can be 'shown' to exist (“There are three kinds of lies: lies, damned lies, and statistics.”- Benjamin Disraeli).
The statistical analysis would only grossly show an overall picture and may not fit in with every individual case (“Statistics largely deals with averages and these averages may be made up of individual items radically different from each other.” —Wilford I. King).
More than statistics, the study design, methodology have to be acceptable to standards and then statistics would help the data to a better understanding.
