Descriptive Measurements: Don't Confuse Your Qs!
Engineers use both qualitative and quantitative descriptions.Copyright 2004 Microsoft Corporation, One Microsoft Way, Redmond, WA 98052-6399 USA. All rights reserved.
Students investigate the difference between qualitative and quantitative measurements and observations. By describing objects both qualitatively and quantitatively, they learn that both types of information are required for complete descriptions. Students discuss the characteristics of many objects, demonstrating how engineers use both qualitative and quantitative information in product design.
Engineers must be able to communicate using both quantitative and qualitative descriptions and specifications. Much of engineering involves translating a client's request into engineering requirements. For example, if a client wants a home that is energy efficient, the engineer might determine a target value for kilowatt-hour use.
After this activity, students should be able to:
- Explain the difference between qualitative and quantitative descriptions.
- Demonstrate that engineers use both qualitative and quantitative information in new product design.
