When going over analogies whole-class, don’t let the students shout out answers, or guess. 0000012423 00000 n Accuracy refers to the agreement between a measurement and the true or correct value. Expanded uncertainty. Synonym Discussion of uncertainty. .�+��m�u~ۡ�@��� Nature hates a void, and even confusing analogies can usually get a mildly-engaged student guessing. σx = uncertainty (error) in measurement Rule For Stating Uncertainties - Experimental uncertainties should be stated to 1-significant figure. In conditions of uncertainty, it’s all the more important to push decision-making outward and downwards, towards where new information is originating and where it can be acted on most swiftly. The football analogy is a good one and encapsulates today’s modern management attitude to uncertainty perfectly where uncertainty is just flagged as another risk, an unmeasured one, and thus can be ignored, if its recognised at all. Consider the analogy of betting odds in a horse race: occasionally a horse with long winning odds (low probability of winning) ... as a ‘measurement uncertainty/error’.
