What is the estimation of error? Write the methods for estimation.
(N/A) The estimation of error refers to the process of determining the maximum possible uncertainty or error in an experimental measurement and expressing it alongside the final result. This provides an indication of the precision and reliability of the measurement.
Error is estimated in three primary ways:
$(1)$ Absolute error: The magnitude of the difference between the individual measured value and the true value (or mean value) of the quantity.
$(2)$ Relative error and Fractional error: The ratio of the mean absolute error to the mean value of the measured quantity.
$(3)$ Percentage error: The relative error expressed as a percentage by multiplying it by $100$.
