How is absolute error different from mean absolute error?

Explain mean absolute error

Explain absolute error

The diameter of a wire as measured by screw gauge was found to be 2.620, 2.625, 2.630, 2.628 and 2.626 cm. Calculate (a) mean value of diameter (b) absolute error in each measurement (c) mean absolute error (d) fractional error (e) percentage error (d) (f) Express the result in terms of percentage error

Write mathematical expression for absolute error and mean absolute error.

If Q = (X^n)/(Y^m) and Delta X is absolute error in the measurement of X, Delta Y is absolute error in the measurement of Y, then absolute error Delta Q in Q is :
