Measuring lengths, precision & errors

Uncertainties in measurement

These worksheets introduce concepts related to precision and uncertainties in measuring length. Precision is related to the smallest divisions on the measuring device (a ruler with divisions of 1/16th of an inch is more precise than a ruler with 1/4" divisions). Uncertainties are related to the natural error in any physical measurement ("plus or minus 1/8").
