Question

what is the formula of relative error

Answer 1

$\mathfrak{\huge{\pink{hello}}}$

The formula is: REaccuracy = (Absolute error / “True” value) * 100%

Answer 2

Answer:

$\frac{(Measured \hspace{1mm} value -Real \hspace{1mm} value)}{Real \hspace{1mm} value}$  is the formula of relative error.

Explanation:

• The slight change in the approximate value and the exact value is called the relative error.
• Due to the error in the measurement or computing machine precision, we get a relative error.

The difference between the measured value and real value divided by the real value gives the relative error.

The formula of the relative error is given as:

$R.E=\frac{(M.V-R.V)}{R.V}$

where $R.E$ is the relative error

           $M.V$ is the measured value.

           $R.V$ is the real value.
