variable

 [var´e-ah-b'l]
something that changes; an attribute or property of a person, event, or object that is known to vary in a given study.
dependent variable in a mathematical equation or relationship between two or more variables, a variable whose value depends on those of others; it represents a response, behavior, or outcome that the researcher wishes to predict or explain.
extraneous variable a factor that is not itself under study but affects the measurement of the study variables or the examination of their relationships.
independent variable in a mathematical equation or relationship between two or more variables, any variable whose value determines that of others; it represents the treatment or experimental variable that is manipulated by the researcher to create an effect on the dependent variable.

variable

(1) Any attribute, phenomenon or event that can have different qualitative or quantitative values. Typically, a form of metadata goes with the variable, there is a variable definition that describes what is varying and there is a value for the variable. Variables are typically assessed in a clinical trial. 
(2) In Study Data Tabulation Model (SDTM), variables describe observations with roles that determine the type of information conveyed by the variable about each observation and how it can be used.

In SDTM, variables include specific subtypes used in clinical research: "study variable" in trial design refers to a variable to be captured on the case record form (CRF); an "assessment" is a study variable pertaining to the status of a subject/patient, is usually measured at a certain time and is usually not compounded significantly by combining several simultaneous measurements to form a derived assessment (e.g., BMI, or a result of statistical analysis); an "endpoint" is a variable that pertains to the trial objectives.

variable

noun Epidemiology Any characteristic or attribute that can be measured.

statistical dependency, between two input variables--total revenue and variable costs, are considered in the simulation.
* Net Revenue Per Pound Invested In Variable Cost: net revenue per invested pound averaged LE 1.97, and ranged between a minimum of LE 1.35 and a maximum of LE 2.6, whereas net revenue per feddan of wheat planted under traditional farming averaged LE 1.63, and ranged between a minimum of LE 1.26 and a maximum of LE 2.08, which means that net revenue per pound invested in wheat planted under terrace farming is 21% higher than that received from wheat planted under traditional farming.
* Variable costs are those costs that would have disappeared within a year if, hypothetically, operations affected by long-distance connections in a connection from Location A to Location B were ceased.
