The degree to which differences exist among a set of scores The standard deviation is usually used to describe the variability of scores in a sample
The property or ability of an organism to change its characteristics from one generation to the other
one of the four characteristics (with inseparability, intangibility and perishability) which distinguish a service; variability expresses the notion that a service may vary in standard or quality from one provider to the next or from occasion to the next Also referred to as Heterogeneity See Services Marketing; Inseparability; Intangibility; Perishability
Variability measures the fluctuations in rates of return These measurements frequently are used as proxies for risk management
(Ticaret) The characteristic of a product or process in which parameters fluctuate to a significant degree but do not typically trend in a specific direction. Reduction of variability is a priority in systems that attempt to ensure consistent quality and reduce lead times
The possible different outcomes of an event As an example, an investment with many different levels of return would have great variability
a characteristic of a variable that refers to how the values assumed by a variable differ from observational unit to observational unit For example, when investigating the numbers of brothers and/or sisters, the responses from one class member to the next would be different
The power possessed by living organisms, both animal and vegetable, of adapting themselves to modifications or changes in their environment, thus possibly giving rise to ultimate variation of structure or function
The characteristic of a product or process in which parameters fluctuate to a significant degree but do not typically trend in a specific direction Reduction of variability is a priority in systems that attempt to ensure consistent quality and reduce lead times
When used in reference to climate, variability refers to the tendency of conditions to vary around some reference point (such as the tendency of the temperature to deviate from some average)
The spread of dispersion of test scores, most often expressed as a standard deviation (See Standard Deviation ) Variance: The square of the standard deviation Back to Top Weighting: The process of assigning different weights to different scores in making some final decision To do weighting correctly, one must convert all scores to a common scale or metric For example, we cannot average temperatures measured with both the Celsius and Fahrenheit scale until the temperatures from one scale are converted to the other scale For educational data, we should first convert all data to a common scale such as a z-score, a T-score, or some other standard score Then, to combine scores, we must determine how much weight to give each score Weights are usually assigned subjectively, based on the importance and/or quality, e g , reliability, of the data Back to Top z-Score: A type of standard score with a mean of zero and a standard deviation of one (See Standard Score )
A measure of the degree to which the scores in a distribution are clustered together or spread apart
The quality of being likely to change or vary over time; lack of uniformity There are two types of variability: temporal and spatial Consider the amount of precipitation HBEF receives annually: in some years the Valley receives more precipitation than the "average year", and in some years it receives less This is an example of temporal variability Spatial variability refers to how different areas in the HBEF may receive different amounts of precipitation in the same period of time (for example, one day or one year)
(used of a device) designed so that a property (as e g light) can be varied; "a variable capacitor"; "variable filters in front of the mercury xenon lights"
A variable is Lisp object that can store an arbitrary value Emacs uses some variables for internal purposes, and has others (known as `options' (q v )) you can set to control the behavior of Emacs The variables used in Emacs that you are likely to be interested in are listed in the Variables Index of this manual See section Variables, for information on variables
An item of data named by an identifier Each variable has a type, such as int or Object, and a scope See also class variable, instance variable, local variable
a quantity that can assume any of a set of values a symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity something that is likely to vary; something that is subject to variation; "the weather is one variable to be considered"
A quantity which may increase or decrease; a quantity which admits of an infinite number of values in the same expression; a variable quantity; as, in the equation x2 - y2 = R2, x and y are variables
(1) A quantity which may take any one of a specified set of values It is convenient to apply the same word to denote non-measurable characteristics, e g "sex" is a variable in this sense since any human individual may take one of two "values," male or female It is useful, but far from being the general practice, to distinguish between a variable as so defined and a random variable or variate (2) Any structural element in an ecosystem that varies over time, also "component " (3)A condition of a system in which elements or a performance measure take different values
A Java name that has scope only from its declaration to the end of the enclosing block Variables are formally called local variables; sometimes, this is abbreviated to locals
A variable is an abbreviation for a sequence of characters, and may appear anywhere that the characters in question could appear Even if the variable contains a number (e g 6 62559e-34) it is still just a characters, although SM may choose to treat them as a number in some contexts (e g the right-hand side of a SET command)
In a system of formal logic, any symbol thatunlike a constantdesignates generally Thus, the propositional calculus employs statement variables, while quantification theory makes use of individual variables Also see OCP
—A typed storage location in memory The type of the variable determines what kind of data it can store Examples of variables include local variables, parameters, array elements, static fields and instance fields See Types
light can be varied; "a variable capacitor"; "variable filters in front of the mercury xenon lights" liable to or capable of change; "rainfall in the tropics is notoriously variable"; "variable winds"; "variable expenses
Something that is variable changes quite often, and there usually seems to be no fixed pattern to these changes. The potassium content of foodstuffs is very variable a variable rate of interest. + variability vari·abil·ity There's a great deal of variability between individuals
A term used in statistics is used to describe the factors that are to be studied Data variables are described as either: 1) Qualitative (Categorical) or
A symbol that can hold different values at different times For example, the variable var1 might hold 55 25 one time a program is run, -32 7 the next time, and different numbers other times Program variables are much like the unknowns in a formula, such as the L and W in this formula: Area = L x W In programs, however, variables often hold different values at different times within the same program A variable can be contrasted with a constant A constant might be the number 150, but a variable might be the symbol dis (short for distance) which can hold 150 or any other number Besides holding numbers, variables often hold strings, lists, etc See also "Local variable," "Global variable," and System variable" above
An element in a model For example, in the model RS&Pt+1 = a + b Tbill t + et, where RS&Pt+1 is the return on the S&P in month t+1 and Tbill is the Tbill return at month t, both RS&P and Tbill are "variables" because they change through time; i e , they are not constant
A variable contains global information that can be accessed in all parts of a model Variables can be of type integer or real They must defined in the Build/Variables menu before they can be used
A value or string that can be changed - think of it as a "box" A variable can contain either a string (a string variable) or a number (a numeric variable) The contents of the "box" can be read or changed at any time You can access the contents of a string variable within any parameter by enclosing the variable name with "#" characters, and similiarly a numeric variable can be accessed inside any parameter by enclosing its name with "%" characters
A variable is an object in Lisp that can store an arbitrary value Emacs uses some variables for internal purposes, and has others (known as `user options' (q v )) just so that you can set their values to control the behavior of Emacs The variables used in Emacs that you are likely to be interested in are listed in the Variables Index in this manual See section Variables, for information on variables
(1) A name that represents a string value Variables that usually are set only on a command line are called parameters Other variables are simply names to which the user or the shell may assign string values (2) In Fortran 90, data object whose value can be defined and redefined A variable may be a scalar or an array (3) In the shell command language, a named parameter See also shell variable
{i} something given to variation; quantity that may represent any one of a set of values (Mathematics); star whose brightness variates at intervals (Astronomy)

A variable is a quantity that can have any one of a set of values. It is conventional to place the independent variable on the right-hand side of an equation. In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation. Commonly used variables include x and y (real-number unknowns), z (complex-number unknowns), t (time), r (radius), and s (arc length). Variables should be distinguished from coefficients, fixed values that multiply powers of variables in polynomials and algebraic equations. In the quadratic equation ax^2 + bx + c = 0, x is the variable and a, b and c are coefficients whose values must be specified to solve the equation. In translating word problems into algebraic equations, quantities to be determined can be represented by variables.

a data array together with all the information attached to it: label (8 characters), descriptor (48 characters), status information (type: 1= numeric variable, 2= GVAR, 3=alpha/the number of cases and a tie) and three associated values minimum, maximum and a reference value (default= median) The user refers to a variable using an integer number referring to the relative position of the variable in the WA Instead of numbers variable labels or ties can be specified using the # substitution When storing a WA in an EDA file variables are packed; i e variables are stored consecutively with no empty variables in between The same can be done by the PACK command Variables can be protected or unprotected and have different usages (type of variable) You should very clearly distinguish letter variables, i e scalar variables and "normal" variables, i e vectors
A variable is a factor that can change in quality, quantity, or size, which you have to take into account in a situation. Decisions could be made on the basis of price, delivery dates, after-sales service or any other variable
A variable is a symbol into which data can be stored As its name implies, the value, or contents, of a variable can change during program execution In the earliest form of BASIC, variable names were typically single alphabetic characters for variables containing numbers and alphabetic characters preceded by a "$" for "string" variables A "string" variable is a variable containing alphabetic and/or punctuation characters In PICK/BASIC, variable names may be of any length and therefore should be descriptively named Variable names must begin with an alphabetic character and may include alphabetic characters, periods and dollar signs
A named storage location that can contain data that can be modified during program execution Each variable has a name that uniquely identifies it within its level of scope Variable names: Must begin with an alphabetic character Can't contain an embedded period or type-declaration character Must be unique within the same scope Must be no longer than 255 characters
text-strings of the form %VARIABLE% that are expanded on the fly into text, image, or any other type of embedded content; predefined variables are coded into the main TWiki package, Plugins variables, and user-specified variables are created in TWikiPreferences, WebPreferences, or single topics
