Measurement and Uncertainty

Measurement and Uncertainty (link)

Note that this is an introductory unit which covers some of the skills required for practical work throughout the course including:
  • Making analog and digital measurements.
  • Significant figures and precision.
  • Decimal places.
  • Absolute, relative and % uncertainty.
  • The treatment (propagation) of uncertainties in calculations.
