Question # 1

Explain the term " precision" and accuracy ?

  • Ans 1: The 'Precision represents the magnitude of error in a measurement while the accuracy means to check how the measured values are closer to the actual value. The accuracy represents the relative error. It can be obtained by dividing the error with measured quantity.
