<prompt> Pearsons formula is used for -Cephalic indexStatureRaceAge  <response>: STATURE The most common method used- linear regression. With this technique, the known statures of adults in a given population are plotted against the lengths of skeletal elements and the best lines are fitted to the scatter plots Various regression formulae for calculating height have been compiled, based on a number of different populations and sex.
