Errors – Solving Master

For known actual value.
1. Absolute error $=$ Actual value $-$ measured value
2. Relative error $= \dfrac{\text{Absolute error}}{\text{Actual value}}$
3. Percentage error $= \dfrac{\text{Absolute error}}{\text{Actual value}} \times 100 \%$
For unknown actual value.
1. Maximum absolute error $=\dfrac{1}{2} \times$ Degree of accuracy
2. Maximum relative error $= \dfrac{\text{Maximum absolute error}}{\text{Measured value}}$
3. Maximum percentage error $= \dfrac{\text{Maximum absolute error}}{\text{Measured value}} \times 100 \%$
