• Oftentimes, this occurs when a machine is calibrated incorrectly or
there is an error in a program being used.
• Systematic error is an error of precision, meaning this error has high
precision and low accuracy. None of the measurements will be
accurate because they are all off by a certain factor.
• The fact that each of the measurements is off by the same amount
leads to the measurements being grouped close together, hence the
precision.

• There are many sources of error in measurement in which some of
the important sources are given here.
• Errors are produced by instruments.
