Measurement Definition in Science Measurement Definition. In science, a measurement is collection of quantitative or numerical data that describes a property of an object or event. A measurement is made by comparing a quantity with a standard unit.

Measurement The type or level of measurement is a taxonomy for the methodological character of a comparison. For example, two states of a property may be compared by ratio, difference, or ordinal preference.

What is Measurement and Uncertainty? Uncertainty as used here means the range of possible values within which the true value of the measurement lies. This definition changes the usage of some other commonly used terms. For example, the term accuracy is often used to mean the difference between a measured result and the actual or true value.

Definition of measure in English: [with object] 1  1Ascertain the size, amount, or degree of (something) by using an instrument or device marked in standard units. 2  2Assess the importance, effect, or value of (something) ‘it is hard to measure teaching ability’. 3  3archaic Travel over (a certain distance or area) ‘we must measure twenty miles today’.

- A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same quantity. Any other value of that quantity can be expressed as a simple multiple of the unit of measurement.

System of measurement A system of measurement is a collection of units of measurement and rules relating them to each other. Systems of measurement have historically been important, regulated and defined for the purposes of science and commerce. Systems of measurement in modern use include the metric system, the imperial system, and United States customary units.

Measuring instrument A Love Meter and Strength tester machine at a Framingham, Massachusetts rest stop. A measuring instrument is a device for measuring a physical quantity. In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events.

The Units of measurement Performing a measurement means comparing an unknown physical (or chemical) quantity with a quantity of the same type taken as reference using an instrument. A measurement necessarily involves a reference frame and therefore units. In the not so distant past, there were numerous units, which had little in common with each other. The first coherent system of units only appeared with the French revolution: the metric system.

Units of measurement Units of measurement. Values, quantities, or magnitudes in terms of which other such are expressed. Units are grouped into systems, suitable for use in the measurement of physical quantities and in the convenient statement of laws relating physical quantities. A quantity is a measurable attribute of phenomena or matter.

Definition of Objective Measurement Definition of Objective Measurement Objective measurement is the repetition of a unit amount that maintains its size, within an allowable range of error, no matter which instrument, intended to measure the variable of interest, is used and no matter who or what relevant person or thing is measured.

Measurement Thus the definition of measurement is: A set of observations that reduce uncertainty where the result is expressed as a quantity.. This definition is implied in what scientists actually do when they measure something and report both the mean and statistics of the measurements.

Definitions &Translations Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained.

measurement method measurement method. The technique or process used to obtain data describing the factors of a process or the quality of the output of the process. Measurement methods must be documented as part of a Six Sigma project or other process improvement initiative, in order to ensure that measurements of improvements to a process are accurate.

Units of measurement A unit is fixed by its definition, and is independent of physical conditions such as temperature. By contrast, a standard is a physical realization of a unit, and realizes that unit only under certain physical conditions. For example, the metre is a unit, while a metal bar is a standard.

Level of measurement Level of measurement. Not to be confused with Level measurement. Nominal variable redirects here. For the economics usage, see Real versus nominal value (economics). Level of measurement or scale of measure is a classification that describes the nature of information within the numbers assigned to variables. Psychologist Stanley Smith Stevens developed the best known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio.

Length Length is a measure of one dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed). In most systems of measurement, the unit of length is a fundamental unit, from which other units are defined.

What is 'Accounting Measurement' What is 'Accounting Measurement'. The computation of economic or financial activities in terms of money, hours or other units. An accounting measurement is a unit of some measurable element that is used to compare and evaluate accounting data. Accounting is often measured in terms of money; for example, when a company records weekly sales at $10,000. The same company could record those transactions in terms of units sold; for instance 5,000 units (of $2.00 products).

Measurement Measurement - Methodology. 1  The measurement of a property may be categorized by the following criteria: type, magnitude, unit, and uncertainty. [citation needed] 2  The type or level of measurement is a taxonomy for the methodological character of a comparison. For example, two states of a property may be compared by ratio, difference, or ordinal preference. The type is commonly not explicitly expressed, but implicit in the definition of a measurement procedure.
