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. As the scientist changes the independent variable, he or she observes what happens.

Variable (mathematics) The term variable comes from the fact that, when the argument (also called the variable of the function) varies, then the value varies accordingly. In more advanced mathematics, a variable is a symbol that denotes a mathematical object, which could be a number, a vector, a matrix, or even a function. In this case, the original property of variability of a variable is not kept (except, sometimes, for informal explanations).

Difference Between Variable and Constant 1 Variable In mathematics, variable is referred to a term which keeps on changing within its limitations and can take up any value as a consequence of any change in the scenario. 2  Some variables are independent and some are dependent. 3  Variables have great significance in algebra and other fields of mathematics.

An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed/controlled by the scientist.To ensure a fair test, a good experiment has only one independent variable.or example, if you open a faucet part way (the independent variable), the quantity of water flowing (dependent variable) changes in response--you observe that the water flow increases. Experiments also have constants or controlled variables.

In biology, what are dependent and independent variables? Anonymous. 1  Those terms carry the same meanings here as they do in any other field. A variable is something in an experiment that is subject to change; an independent variable is something the experimenter changes; and the dependent variable is what is measured by the experimenter (also, it depends on the independent variable).

- 1 Independent variable is a variable in an equation, whose values make up the domain. 2  In other words, an independent variable in an equation may have its value freely chosen regardless the values of any other variable.

- a constant or variable term in a function that determines the specific form of the function but not its general nature, as a in f (x) = ax, where a determines only the slope of the line described by f (x). one of the independent variables in a set of parametric equations.

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.

Online Math Dictionary: V In Algebra, a variable is the letter in an equation that represents an unknown number. Examples: 2x + 5 = 7 2x - 3y = 6. A vector is a ray that has a magnitude (length) and a direction (which way it's pointing.) Vectors are used a lot in physics and navigation.

Difference Between Variable and Constant Variable and constant are two commonly used mathematical concepts. Simply put, a variable is a value that is changing or that have the ability to change. A constant is a value which remains unchanged.

- Variables are usually denoted by X and Y. The independent variable is identified as the X-variable and is plotted on the X-axis or abscissa of a graph, and the dependent variable is defined as the Y-variable and is plotted on the Y-axis or ordinate.

Types of Variable A variable is not only something that we measure, but also something that we can manipulate and something we can control for. To understand the characteristics of variables and how we use them in research, this guide is divided into three main sections.

Variables, Functions and Equations Variables are called variables because they vary, i.e. they can have a variety of values. Thus a variable can be considered as a quantity which assumes a variety of values in a particular problem. Many items in economics can take on different values.

Variable (mathematics) An independent variable is a variable that is not dependent. The property of a variable to be dependent or independent depends often of the point of view and is not intrinsic. For example, in the notation f(x, y, z), the three variables may be all independent and the notation represents a function of three variables.

Variable and attribute (research) In science and research, attribute is a characteristic of an object (person, thing, etc.). Attributes are closely related to variables. Variable is a logical set of attributes.Variables can vary - for example, be high or low.How high, or how low, is determined by the value of the attribute (and in fact, an attribute could be just the word low or high).(For example see: Binary option).n science and research, attribute is a characteristic of an object (person, thing, etc.). Attributes are closely related to variables. Variable is a logical set of attributes.

- The portion of the equation denoted by a + b X i defines a line. The symbol X represents the independent variable. The symbol a represents the Y intercept, that is, the value that Y takes when X is zero. The symbol b describes the slope of a line.

Writing Algebraic Expressions Summary: A variable is a symbol used to represent a number in an expression or an equation. The value of this number can change. An algebraic expression is a mathematical expression that consists of variables, numbers and operations. The value of this expression can change.
