Uncertainty Flashcards
1
Q
What is uncertainty?
A
The amount of error your measurements might have. The results you get from an experiment won’t be completely perfect - there’ll always be a degree of uncertainty in your measurements due to limits in the sensitivity of the apparatus
2
Q
What is the uncertainty value of a piece of measuring equipment
A
+/ - half the value of the smallest unit of precision
Eg a 30cm ruler - smallest unit is 1mm so the uncertainty would be +/- 0.5mm
3
Q
What do you do if you’re combining measurements?
A
Combine there uncertainties
4

How can you calculate percentage error?
A
