How do you calculate uncertainty?
The uncertainty of a measuring instrument is estimated as plus or minus (±) half the smallest scale division. For a thermometer with a mark at every 1.0°C, the uncertainty is ± 0.5°C. This means that if a student reads a value from this thermometer as 24.0°C, they could give the result as 24.0°C ± 0.5°C.
How do you calculate uncertainty examples?
For example, if you weigh something on a scale that measures down to the nearest 0.1 g, then you can confidently estimate that there is a ±0.05 g uncertainty in the measurement. This is because a 1.0 g measurement could really be anything from 0.95 g (rounded up) to just under 1.05 g (rounded down).
How do you calculate uncertainty in physics?
A common rule of thumb is to take one-half the unit of the last decimal place in a measurement to obtain the uncertainty. Rule For Stating Uncertainties - Experimental uncertainties should be stated to 1- significant figure.
