measurement error
Instrument reading deviation
Measurement error is the difference between a measured value and the true value of what's being measured.
All measurements contain some error—from imprecise instruments, human limitations, or environmental factors.
In statistics and research, measurement error affects data reliability: The survey results include measurement error from respondents misremembering dates.
Systematic errors skew consistently in one direction; random errors vary unpredictably.
