Types of Errors

  • Absolute Error (a) – The difference between the true value and the individual measured value of the quantity is called the absolute error of the measurement.

    • Suppose a physical quantity is measured n times and the measured values are a1,a2,a3...an. The arithmetic mean (am) of these values is –

Propagation of Errors in Mathematical Operations

  • Rule I – The maximum absolute error in the sum or difference of the two quantities is equal to the sum of the absolute errors in the individual quantities. If Z=A+BORZ=AB and if ±A and ±B represents the absolute errors in A and B respectively, then the maximum absolute error in Z=Z=A+B and
