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.
