Mathematical and statistical techniques to analyse data
What is uncertainty?
Syllabus: assess and evaluate the uncertainty in experimental evidence, including but not limited to:
– systematic errors
– random errors
The degree to which you are uncertain of your calculated average.
What is absolute uncertainty?
Syllabus: assess and evaluate the use of errors in:
– mathematical calculations involving degrees of uncertainty
– graphical representations from curves of best fit
Absolute uncertainty is calculated as the maximum variance from the mean, so: x±y
x: mean
y: absolute uncertainty
How do you calculate percentage uncertainty?
assess and evaluate the use of errors in:
– mathematical calculations involving degrees of uncertainty
– graphical representations from curves of best fit
z = x/y x 100
x: mean
y: absolute uncertainty
z: percentage uncertainty
How do you add or subtract uncertainties
Use the absolute uncertainty
