(6 cards)
1
Q
Resolution (of an instrument)
A
The smallest non-zero reading that can measured
2
Q
Zero errors
A
A specific systematic error we’re the instrumental does not read zero when the quantity should be zero.
3
Q
Systematic error
A
When a measuring instrument consistently reads changes in the quantity to be a scale factor greater or less than the actual change.
4
Q
Random error
A
When measured quantities differ from the average mean value
5
Q
Accuracy
A
Refers to results which when averaged give the accepted value of a variable within an experimental uncertainty.
6
Q
Precision
A
Refers to the number of significant figures or decimal places with which a measurement can be made.
