Oops, I Did It Again: Errors in Measurement

by: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo

Understanding the precision and accuracy of measurements is a crucial skill that scientists must develop to do their work. All measurements involve some degree of error. Knowing how to assess and work with error is an essential part of making sense of scientific observations. What is accuracy? What is precision? How do we make our measurements more accurate or precise? Why would two measurements of the same object yield different values? How can error in measurement be reduced? Students investigate these questions through a series of measurement tasks involving heights, mass, and different scales of measurement.
