WebJun 13, 2024 · How do you find the uncertainty? 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. Why are graduated cylinders not accurate? WebIt depends whether the 0.5 uncertainty represent a property of the cylinder (systematic error) or if the cylinder is perfect and 0.5 represent random error in reading the cylinder. …
