HF 300 EXAM 3 QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED GRADED A++
what is the definition of anthropocentric?
"measure of man"
-study the measurement of human dimensions.
-typically used to alter designs based on body dimensions
why do we need Anthropocentrics in human factors
What are the different types of anthropometric variability?
-Age
-Gender
-Occupation
-Heredity
-generation
-Diurnal
What does anthropometric variability in generation mean?
Body dimensions change over history
What is biocular breadth? What design does it have the greatest impact upon?
The cross between Sitting height and forward reach.
as described in the Dimension chart
Why are statistics important for anthropometrics?
, To be able to measure the changes in the body
What's the difference between a population and a sample?
Population: some theoretical group of people being measured
Sample: the group of people actually measured
What's the difference between designing for an average, an extreme, or an
adjustable range?
A normal curve (typical data follows a typical pattern):
Extreme 5%
adj Range 90%
What's the difference between a structural measurement and a functional
measurement? Think of an example.
Structural: While Stationary
Functional: while moving
What are four different ways to adjust the system to account for flexibility in an
anthropometric design?
Workplace: reconfigure whole thing
Worker: change the persons position
Workpiece: alter the item itself
