===Meaning===&lt;br /&gt;
[[Uncertainty]] is the amount by which a [[reading]] may be different from the true value.&lt;br /&gt;
&lt;br /&gt;
===About Uncertainty===&lt;br /&gt;
: [[Uncertainty]] is caused by [[Random Error|random errors]] which take place during an [[experiment]].&lt;br /&gt;
: The [[uncertainty]] in a [[reading]] can be found by [[repeat]]ing the [[reading]] and halving the [[range]] of those [[reading]]s.&lt;br /&gt;
&amp;lt;math&amp;gt;Uncertainty=\frac{range}{2}&amp;lt;/math&amp;gt;.&lt;br /&gt;
: The [[uncertainty]] in a [[result]] is how far above or below the [[Mean Average|average]] [[result]] the true value may be.&lt;br /&gt;
===Examples===&lt;br /&gt;
