The variability of biological measurements is considerably greater than that of most physical, chemical or technical data. The greater the variability or scatter, the more difficult to be certain of a difference between two observations (e. g. duration of a disease with or without treatment; comparison of the efficacy of two drugs). The examples to be quoted of distributions of measurements, comparisons of treatment groups, or percentages have been calculated by methods which are constantly occurring in medical papers. It is important to understand the principles involved.
