Vedclass · Answer

(A) Absolute error is defined as the difference between the measured value and the true value of a physical quantity. Since it represents a physical quantity,it has the same units as the measured quantity.Relative error is defined as the ratio of the mean absolute error to the mean value of the quantity. Since it is a ratio of two quantities with the same units,the units cancel out,making it a dimensionless quantity.Fractional error is essentially the same as relative error (often expressed as a percentage when multiplied by $100$),and it is also dimensionless.Therefore,absolute error has a unit,whereas relative and fractional errors have no units.

Out of absolute error,relative error,and fractional error,which has a unit and which has no unit?
