Anthropometrics

We learned in the previous section that there are individual differences in human characteristics and that these follow a normal distribution.   This is true with anthropometric measurements. 

You may have heard the expression "to design for the 5th percentile female to the 95th percentile male."  This means that for the selected anthropometric measure, such as height, the lower limit of our range is the height of a 5th percentile female and the upper limit is the height of a 95th percentile male.  This range accommodates 90% of the population for that one selected measure.

Graph illistrating that 90th percent of the populations height is between the 5th percentile of females and the 95th percent of males.
