Understanding Experimental Error - Las Positas College
www.laspositascollege.eduOne type of measurement uncertainty is due to instrumental resolution. If you are trying to measure the length of a piece of string, the precision of your length measurement depends on what type of ruler you use to measure the length. The smaller the tick marks on your ruler, the more precise your measurement.
