Errors in Measurement
Absolute Error = |Measured Value − True Value|
Mean Absolute Error = (Σ|Δa_i|)/n
Relative Error = Mean Absolute Error / Mean Value
Percentage Error = Relative Error × 100
Combination of Errors
Error in Sum: Δx = Δa + Δb
Error in Difference: Δx = Δa + Δb
Error in Product: (Δx/x) = (Δa/a) + (Δb/b)
Error in Division: (Δx/x) = (Δa/a) + (Δb/b)
