Whenever you measure the length of a stick, or the period of a pendulum, or the mass of a whale, or ANYTHING, you should end up with two results:
How do you determine the uncertainty in a measurement? The long answer is given in the guides to uncertainties (see them listed in the For more information section below). The short answer is that you may either
Okay. Suppose that you have made some measurements, and written down the value and uncertainty of each one. If you have to combine the measurements to derive some result, how do you combine the uncertainties to find the uncertainty in the result? There are several approaches one can take. Again, read the guides below for detailed descriptions. We will follow two of these methods in class today.
