absolute error=Δx where x is any variable.Relative Error: Relative error gives an indication of how good a measurement is relative to the size of the thing being measured. Let’s say that two students measure two objects with a meter stick. One student measures the height of a room and ...
Absolute error is defined as the difference between the actualvalueand the measured value of a quantity. The importance of absolute error depends on the quantity that we are measuring. If the quantity is large such as road distance, a small error in centimetres is negligible. While measuring th...

Relative Error Formula The ratio of absolute error to the actual value of the quantity is used to determine the relative error. The relative error can be calculated using the formula below if x is the actual value of a quantity, x’ is the measured value of the quantity, and x” is ...
