Measurement is the
process of obtaining a numerical value representing a physical property, such
as length, mass, or time, by way of a unit of measurement. A u
nit of measurement is a magnitude
representing a physical quantity by use of
a standard for measurement of that physical quantity.
A measuring device is a piece of
equipment used to measure a physical quantity based on a standard for
measurement.
Measurement and Objectivity
Measurements are the most objective part of science since
the resulting numbers are what they are. The mechanical devices used for measurement
aide objectivity by removing the human factor that is human subjectivity. The validity
of a measurement is only as valid as the theory behind it.
