Parallax error |
Error because of the angle of view from the scale. |
Beaker |

|
Uncertainty on Analogue scale |
± 1/2 smallest scale division |
|
|
|
Uncertainty on digital scale |
± smallest scale division |
|
|
|
Combining uncertainties: a + b |
Uncertainty = (±∆a) + (±∆b) |
|
|
|
Combining uncertainties: a×b or a÷b |
Uncertainty = (±%∆a) + (±%∆b) |

|
What are the types of uncertainty and what do they mean? |
Random - repeat measurements which give slightly different results
Systematic - affects all results in the same way - caused by technique - caused by zero error on device ( value if nothing, taring) |
|
|
|
How do you measure the gradient uncertainty? |
±(max gradient - min gradient) ÷ 2 |
