  Uncertainty in a derived quantity can then be estimated from the number of significant figures and/or decimal places given by the appropriate rule. This lab will be graded heavily on correct propagation of uncertainty (by way of significant figures rules) in derived quantities.

  This is then called the Absolute uncertainty. eg. 25.4 ± 0.1 s. The symbol for absolute uncertainty is dx, where x is the measurement: In the example: x =25.4 and dx = 0.1 The absolute uncertainty is often converted to show a Percentage or Fractional uncertainty. For the above example, this would be: 25.4 ± 0.4% s (0.1 s / 25.4s x 100% = 0.4%).

  To learn to express measurements and uncertainty as absolute and relative values. Introduction. When reporting a measured value, we must always state the uncertainty of the measurement; that is, we must be able to state the range of possible range of values within which we believe the true value of the measurement lies.

  relative uncertainty = 55.3536 cm2 ± 1.0752% = (55.3536 ± 0.5952) cm2 Change the relative uncertainty into absolute. 1.0752% of 55.3536 cm2 = 0.5952 cm2 = (55.3536 ± 0.6) cm2 Round uncertainty to 1 significant digit = (55.4 ± 0.6) cm2 Round result to same decimal place as unc. This is written appropriately for final answer
