===About Precision===
: [[Results]] may be said to be '''precise''' if each [[repeat]]ed [[result]]s is close to the same [[value]].: The smaller the [[uncertainty]] the greater the '''precision'''.: '''Precision''' is achieved by:
:*Using [[Measuring Instrument|instrument]]s with a high [[resolution]].
:*[[Control Variable|Controlling]] [[variable]]s so that [[reading]]s are stable over a long period of [[time]]. Sometimes [[reading]]s fluctuate so they cannot be recorded to as many [[Significant Figures|significant figures]] as the [[Measuring Instrument|instrument]] shows.
