Outcomes
(a) Describe and explain:
(i) factors affecting accuracy and
uncertainty of measurements
(ii) the importance of recognising the largest source of
uncertainty in a measurement.
(b) Make appropriate use of:
(i) SI units and their prefixes,
standard form, angles in degrees and radians
(ii) the terms: accuracy, precision, resolution,
sensitivity, response time, uncertainty, systematic error including zero error
by sketching and interpreting:
(iii) simple plots of the distribution of measured values to
estimate the mean (or median) value and the spread and to identify potential
outlying values and to suggest reasons to account for them
(iv) a variety of different kinds of graphical plot and use
of uncertainty bars to help establish the validity of measured data.
(c) Make calculations and
estimates involving:
(i) uncertainty of experimental
data, the mean of results, range, spread and percentage uncertainties. Estimate
of best fit gradients and intercepts with uncertainty
(ii) estimating uncertainties when data are combined by
addition, subtraction, multiplication, division and raising to powers
(iii) estimated magnitudes of everyday quantities.
