Limitation of physical measurements

What is the difference between error and uncertainty in a measurement?

A
  • Error: the variation between repeated measurements.
  • Uncertainty: the smallest scale division on the instrument.
B
  • Error: the percentage difference between repeated values.
  • Uncertainty: the mean value calculated from the readings.
C
  • Error: the estimated range in which the true value lies.
  • Uncertainty: the difference between the measured and true value.
D
  • Error: the difference between the measured and true value.
  • Uncertainty: the estimated range in which the true value lies.
