Measurement error(redirected from Observational error)
Also found in: Medical, Wikipedia.
The difference between the value of some quantity and the value obtained by measuring it. It is nearly impossible to attain accurate measurements all the time, especially when one uses a single means of calculation. For this reason, when measuring the value of a company or asset, many analysts will check and double-check their work, and perhaps calculate the value using a different method, in order to ensure accuracy.
