When you take an electrical measurement, though, you use an instrument to measure an unknown, infinitely divisible quantity. The number of digits you have in an instrument and the instrument’s ...

But back to the uncertainty, here are some options: Record your measurements to the appropriate significant figures. Use the sig-fig rules to determine the uncertainty in the calculation.

I am not saying significant figures are entirely stupid ... One way is to include an uncertainty value with any measurement (or calculation). In this way, the time for the apple to fall from ...

Students distinguish between accuracy and precision of measurements. Accuracy, Precision, and Significant Digits: Students distinguish between accuracy and precision of measurements and make ...

Nearly 90 years after Werner Heisenberg pioneered his uncertainty principle ... the statistical data provided by the measurement at hand, so that the numbers one identifies as "errors" are ...
