UNCERTAINTY IN MEASUREMENTS
In this unit you will investigate the uncertainty in measurement and consider the difference between accuracy and precision. Since measurements are approximations, calculations with measurements have some degree of error; thus, you will determine absolute and relative error and examine the effects of errors on calculated measurements. You will also find the number of significant digits for calculated measures.
