always have a degree of u certainty because of unavoidable error
MEASUREMENTS
63
deviation of a measured value from the expected or true value
ERROR
64
way of expressing error
UNCERTAINTY
65
measured value true plus uncertainty
EQUATION
66
refers to the closeness of measured value to the expected or true value of a physical quantity
ACCURACY
67
represents how close or consistent the independent measurement of the same quantity are to one another
PRECISION
68
how far/close to the target
ACCURACY
69
frequency of same results over time

uncertainty of a measurement expressed un the same units as the quality measurements
ABSOLUTE UNCERTAINTY
83
ratio of the absolute uncertainty to the measured value
RELATIVE UNCERTAINTY
84
measuring devices have finite precision, which introduces uncertainty
