dependent variable In mathematics, a variable whose value is determined by the value of an independent variable. For example, in the formula for the area of a circle, A = πr2, A is the dependent variable, as its value depends on the value of the radius (r). Compare independent variable.

Variable (computer science) Variable (computer science) In computer programming, a variable or scalar is a storage location paired with an associated symbolic name (an identifier), which contains some known or unknown quantity of information referred to as a value.

Independent variable Independent variable. Definition. noun, plural: independent variables. (1) The variable in a functional relation whose value is independent, or is not affected by other variables. (2) The variable that is manipulated in an experiment. (3) The factor that affects the value of variables dependent to it. Supplement.

Dependent variable Home » Dependent variable. Definition. noun, plural: dependent variables. (1) The variable in a functional relation whose value is dependent upon, or influenced by, an independent variable. (2) A factor whose value changes when the independent variable is changed. (3) The variable whose value is measured to determine the extent of the effect of another variable to it, as in an experiment. An experiment is designed to see if a newly developed drug is effective in treating patients with cough.

Variable (computer science) The value of a computing variable is not necessarily part of an equation or formula as in mathematics. In computing, a variable may be employed in a repetitive process — assigned a value in one place, then used elsewhere, then reassigned a new value and used again in the same way (see iteration).

What are Variables in Science? - Definition, Types & Examples In science, a variable is any item, factor, or condition that can be controlled or changed. There are three types of variables in scientific experiments, but we will define them later in the lesson. First, let's discuss why scientists use experiments.

Variables Continuous variable: A numerical variable that can have any number. If dependent and independent variables are both continuous, then the data can be represented by a line graph. Discrete variable: A variable that involves simple numbers or a physical quantity with measured values that are quantized.

Variables in Your Science Fair Project These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.The independent variable is the one that is changed by the scientist. To ensure a fair test, a good experiment has only one independent variable. variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

Australian Bureau of Statistics A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables. It is called a variable because the value may vary between data units in a population, and may change in value over time.

- Variables and Scales of Measurement. Variables. A variable is simply anything that varies, anything that assumes different values or categories. For example, sex varies because there is more than one category or classification: female and male. Race is a variable because there is more than one category: Asian, Black, Hispanic, etc.

What passes through stomata? Water Vapor, CO2 and O2 pass through stomata. The Stomata are located on the underside of the leaf (lower epidermus) in order to prevent water loss from direct sunlight via ev … aporation. The upperside (spper epidermus) of the leaf prevents water loss by evaporation.

- Defining Variables. Variables can be defined as any aspect of a theory that can vary or change as part of the interaction within the theory. In other words, variables are anything can effect or change the results of a study. Every study has variables as these are needed in order to understand differences.here is no limit to the number of variables that can be measured, although the more variables, the more complex the study and the more complex the statistical analysis. The most powerful benefit of increasing our variables, however, is control.

- Independent Variable. A variable in an equation that may have its value freely chosen without considering values of any other variable. For equations such as y = 3x – 2, the independent variable is x. The variable y is not independent since it depends on the number chosen for x. Formally, an independent variable is a variable which can be assigned any permissible value without any restriction imposed by any other variable.

What Is a Variable in Science? Types of Variables. Independent Variable The independent variable is the one condition that you change in an experiment. Example: In an experiment measuring the effect of temperature on solubility, the independent variable is temperature. Dependent Variable The dependent variable is the variable that you measure or observe.

Variable (mathematics) A constant, or mathematical constant is a well and unambiguously defined number or other mathematical object, as, for example, the numbers 0, 1, π and the identity element of a group. Here are other specific names for variables. 1  A unknown is a variable in which an equation has to be solved for.

Variables Continuous variables. A variable is said to be continuous if it can assume an infinite number of real values. Examples of a continuous variable are distance, age and temperature. The measurement of a continuous variable is restricted by the methods used, or by the accuracy of the measuring instruments.
