Human Factors Model > Human Variance > Anthropometrics - 3 of 4
Anthropometrics (continued)

We again use the concept of "population."  This is important in anthropometrics as there are differences in size and body segment proportions due to age, gender, and ethnicity.  So, to properly select the data to use, we must know something about our population composition, and we must know what percentage of the population we wish to accommodate.  The anthropometric range will be much different if we are designing products for male, professional basketball players than if we are designing for the general public.
