  6. Human Factors Engineering • We expect to live and work in environments that fit us as human users. • The degree to which things in our environments are comfortable is a measure of good planning and the application of “ergonomics.” • Ergonomics – the design of products, as well as of working and living space, to fit the needs of humans.

  7. Human Scale • Not all things are designed for the average person. • Anthropometrics – the branch of science that deals with human measurement by describing human size, shape, and other characteristics. • Descriptive statistics

  8. Statistics • Probability – likelihood of some event happening. • Normal distribution – bell curve • Mean score – average • Percentiles • Standard deviation - how far from the mean
