Ergonomic Design

The term “ergonomics” refers to the practice of designing products and systems that accommodate the physical limitations of the human body.  Engineers consider these limitations and how to apply this information to the design of products so that people can use them safely, comfortably, and easily.  Ergonomically designed products reduce the chance that people who use them will experience discomfort or injury.  In this activity students will measure the dimensions of the human body to evaluate the design of a classroom chair. They will collect data, use statistical graphs and charts to represent their data, and then determine if the chair is appropriately designed and sized for the students in their class.

Curricular Subjects: 
Collecting Data, Ordering Rational Numbers, Calculating and Comparing Measures of Central Tendency (Range, Mean, Median, Mode, Lower and Upper Quartiles), Box-and-Whiskers Plots, Standard Deviation, Normal Distribution
