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.

Unit of measurement A unit of measurement is a definite magnitude of a physical quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same physical quantity.Any other value of the physical quantity can be expressed as a simple multiple of the unit of measurement.he definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day. Different systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system.

Definitions &Translations Measuring instrument. 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.easuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty.

Introduction to Measurement and Statistics Normally, when one hears the term measurement, they may think in terms of measuring the length of something (e.g., the length of a piece of wood) or measuring a quantity of something (ie. a cup of flour).This represents a limited use of the term measurement.

Measurement uncertainty The measurement uncertainty is often taken as the standard deviation of a state-of-knowledge probability distribution over the possible values that could be attributed to a measured quantity.

Measurement Measurements are ways that we tell others how much of an item we have. There are two systems of measuring things—English and Metric. English measurements are used only in the United States, while metric measurements are used in nearly every other country. Measurements are used to give number values to distance (length, width, and height), weight, time, volume (liquid measurements), and temperature. To get you used to these measurements, we’re providing a list of commonly used English and metric measurements, and their equivalents.

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’.

Measure (mathematics) In mathematical analysis, a measure on a set is a systematic way to assign a number to each suitable subset of that set, intuitively interpreted as its size. In this sense, a measure is a generalization of the concepts of length, area, and volume.

Measurement However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales. Measurement is a cornerstone of trade, science, technology, and quantitative research in many disciplines. Historically, many measurement systems existed for the varied fields of human existence to facilitate comparisons in these fields.

Measurement Deciding by observation the amount of a given property a subject possesses is called measurement. In a more liberal sense, the term measurement often refers to any instance of systematic observation in a scientific context. Measurement is always an empirical procedure, such as reckoning the mass of an object by weighing it, or evaluating the amount a student has learned by giving an examination.

Measurement uncertainty In metrology, measurement uncertainty is a non-negative parameter characterizing the dispersion of the values attributed to a measured quantity. The uncertainty has a probabilistic basis and reflects incomplete knowledge of the quantity. All measurements are subject to uncertainty and a measured value is only complete if it is accompanied by a statement of the associated uncertainty. Relative uncertainty is the measurement uncertainty divided by the measured value.

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.

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.

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.

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.

Measurement In the classical definition, which is standard throughout the physical sciences, measurement is the determination or estimation of ratios of quantities. Quantity and measurement are mutually defined: quantitative attributes are those possible to measure, at least in principle.n the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures.

Measurement Common English Measures. The metric system is also divided into different categories of measurement, but it has a base unit for each category. A base unit means that that is what the category is usually (but not always) measured in, and all the other terms of measurement in that category are built from the base unit.

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.

Unit of measurement Measurement is a process that uses numbers to describe things based on what we can observe about them. This is done to be able to compare them to each other. We can measure how big things are, how warm they are, how heavy they are, and lots of other features as well. Units of Measurement provide standards for our comparisons, so that the numbers from our measurements refer to the same thing. For example, the metre is a standard unit to measure length.
