Which term describes the application of scientific information concerning the relationship between humans and the design of products, systems, and environments?

• A. Ergonomics
• B. Fatigue
• C. Human factors
• D. Interval data

Answer: (A)

Ergonomics is the practice of applying scientific knowledge about how people interact with tools, tasks, and surroundings to design products, systems, and environments that fit people well. It considers body size and strength, perception and cognition, and the context of use to improve safety, comfort, and performance. The description in the question directly matches this idea: using science about the human–design relationship to shape the way things are made and arranged. While human factors is a closely related term often used in the same context, the wording most precisely describes ergonomics as the applied design discipline. Fatigue and interval data refer to different concepts and don’t capture this design-focused relationship.
