Statistics for a composite distribution in anthropometric studies

Pages 189-198 | Published online: 09 Nov 2010
 

Abstract

It is a fact that in many countries around the world an international community coexists in a certain country either because of business contracts, such as developing countries (e.g. Saudi Arabia), or due to massive immigration to industrialized countries (e.g. United States). The mixed body of various origins live together and share the same work places. In anthropometric designs, care should be taken to accommodate the user population. When anthropometric statistics and distributions are available for the individual nationals there will not be a need to reinvent the wheel. This study demonstrates a technique to pool the available anthropometric information and use this for designs for the composite population. An algorithm is developed to find pertinent statistics such as the mean, the standard deviation and some percentiles. Formula derivation is possible for the mean and the standard deviation, but because of the complexity of the composite distribution, the percentiles are found by numerical integration. A computer program is prepared to compute these statistics.
