Summary

30-page illustrated guide to fundamentals of measurement. This is intended to be a clear, comprehensive overview of effective measurement technique. Intended for advanced high school or introductory college level students. Includes worked examples and problems.

Learning Goals

After reading this packet, and doing the problems, students should be able to:
  • Distinguish between error and uncertainty

  • Recognize that all measurements have uncertainty

  • Identify types of error and sources of error and how to detect/minimize error

  • Estimate, describe, and express uncertainty in measurements and calculations

  • Using uncertainty to describe the results of their own lab work

  • Compare measured values and determine whether values are the same within stated uncertainty

Context for Use

This packet is intended to be used as a short text to introduce students to measurement and uncertainty. Students should learn this material at the beginning of the course as an introduction to lab activities. The material can be presented in lecture format, or assigned as reading. Either way, students should complete with activities designed to help students practice these skills, such as the ruler drop activity. For additional information about this approach see How to Integrate Measurement and Uncertainty
