Uncertainties Flashcards
1
Q
Systematic Error
A
When the measurements differ from the true values by a consistent amount every time the quantity is measured
2
Q
Zero Error
A
When the quantity’s measure should be zero but isn’t
3
Q
Random Error
A
Measurement errors where measurements vary unpredictably
4
Q
Precision
A
How similar/ close repeated measurements are to each other
5
Q
Accuracy
A
How close a measurement is to its true value
6
Q
Absolute Uncertainty
A
A measurement of the actual amount by which the quantity is uncertain
7
Q
Percentage Uncertainty
A
(Absolute Uncertainty/ Measured value) x100%
