Explain mean absolute error

Write mathematical expression for absolute error and mean absolute error.

The ratio of absolute error to the exact value is "_______" .

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 :

What do you understand by absolute error ?

Following observations were taken with a vernier callipers while measuring the length of a cylinder : 3.29 cm,3.28 cm,3.31 cm,3.28 cm,3.27 cm,3.29 cm,3.20 cm . Then find : (a) Most accurate length of the cylinder (b) Absolute error in each observation (c) Mean absolute error (d) Relative error (e) Percentage error Express the result in terms absolute error and percentage error.

The measure of the radius of a sphere is (3.00pm2%) cm. Calculate the percentage error in volume and area. Also calculate the absolute error in volume and surface area.

There are certain number of students in a class. This is approximated to nearest hundreds. Approximate value is 600 and the absolute error is 25. If exact value is less than the approximated value, then fond the relative error. (Correct to two decimal places).

The mean time period of second's pendulum is 2.00 s and mean absolute error in the time period is 0.05s. To express maximum estimate of error, the time period should be written as
