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.
