There is a need for scaling of percentiles, based on mathematical-statistical tools, till charts and tables become
available, generated through reliable-indigenously-collected data. Based on height and mass data of 1666
children, collected from all over Pakistan during 1998-2016, modified-scaled percentiles are generated. Parabolic
curves are fitted to obtain 2 equations by mapping medians of height-data-CDC percentiles to modified-scaled
percentile (50P ), which come out to 43.21P (CDC — Centers for Disease Control and Prevention ) for boys and
34.85P (CDC) for girls. Circles are fitted to derive 2 equations by mapping medians of mass-data-CDC
percentiles to modified-scaled percentile (50P ), which come out to 22.99P (CDC) for boys and 19.93P
(CDC) for girls. The method is general and could be applied to populations of other countries, like, Turkey, provided a large
data sample (of heights and masses) is available. To illustrate the method, builds of a gymnast are determined
based on modified-scaled percentiles.
