==Key Stage 3==
===Meaning===
[[Experimental Error]] is mistakes in the [[results]] of an [[experiment]] that happen because of a problem with the [[method]] or the [[measure|measuring]] [[equipment]].

===About Experimental Errors===
: '''Experimental errors''' lead to [[results]] that are not [[accurate]].
: The smaller the [[reading]] or [[measurement]] taken, the more important the '''error''' becomes. A [[measurement]] of 10 seconds with a 0.2 second '''error''' is less [[Accuracy|inaccurate]] than a 0.5 second [[measurement]] and a 0.2 second '''error'''.
'''Experimental error''' may be:
*A [[Random Error]] when a [[Control Variable]] that has not be controlled properly.
*A [[Human Error]] when a [[human]] does not [[reading|read]] a measuring instrument properly.

*A [[Systematic Error]] when the [[results]] wrong by the same amount each time.
*A [[Zero Error]], a type of [[Systematic Error]], caused by a [[Measuring Instrument|measuring instrument]] not being [[calibrate]]d.
