Question

how do we calculate percentage error

Answer 1

Relative error * 100 gives the percentage error

Answer 2

hello friend ...!!


• Formula used to calculate % error is

P. E = R.E X 100

here R. E represents relative error,

relative error is nothing but the ratio between the mean average error and average error.

example :

1) if the mean average error = 0.048 and average error = 2.14 calculate the percentage error :

answer :

% error =
$\frac{0.048}{2.14} \times 100$

therefore

P.E = 4.8 / 2.14

therefore,

P. E approximately is equal to 2%
