HUMAN FACTORS IN DESIGN

ANTHROPOMETRIC DATA

Vast amount of information is available on-line

Percentile

One of a set of points on a scale arrived at by dividing a group into parts in

order of magnitude.

For example, a score equal to or greater than 97 percent of those attained

on an examination is said to be in the 97th percentile.

Estimates proportions of the data that should fall above and below a given

value.

WHAT IS A PERCENTILE?

SIZE VARIATIONS IN A POPULATION

In general body heights and body lengths do vary uniformly in

a population because they depend upon bone structure.

Taller than 97.5% of population

Taller than 50% of population

Taller than 2.5% of population

WEIGHT VARIATIONS IN A POPULATION

In general weights and widths may not vary uniformly since these measurements depend upon age, amount of body fat, musculature, etc.
