what is the independent and dependent variable in science?
47616
Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable.

Dependent and independent variables. From Wikipedia, the free encyclopedia. In an experiment, the variables used can be classed as either dependent or independent variables. The dependent variable is the possible outcome of the experiment; the effect. It depends on what happens to other variables in the experiment.

They're independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It's what changes as a result of the changes to the independent variable. An example of a dependent variable is how tall you are at different ages.

A dependent variable is what you measure in the experiment and what is affected during the experiment. ... It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.

The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected.

An independent variable is the variable you have control over, what you can choose and manipulate. ... A dependent variable is the variable being tested in a scientific experiment. The dependent variable is 'dependent' on the independent variable.

The independent variable is "independent" because its variation does not depend on the variation of another variable in the experiment/research project. The independent variable is controlled or changed only by the researcher. This factor is often the research question/hypothesis behind the outcome of the experiment.

The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

The independent variable is the variable that is not affected by other variables. Instead, it determines the value of other variables (particularly, the dependent variables). In experimental sciences in particular, it is the variable that is manipulated or controlled by the experimenter.

An independent variable is the factor that has some influence or impact on the dependent variable.

Independent variables - The values that can be changed or controlled in a given model or equation. They provide the "input" which is modified by the model to change the "output." Dependent variables - The values that result from the independent variables.

They are alternatively called these names because of their role in research experiments. Independent variables are the variables that determine how dependent variables vary, i.e. they predict dependent variables. Dependent variables, on the other hand, are the variables being predicted by the independent variables.

The independent (or manipulated) variable is something that the experimenter purposely changes or varies over the course of the investigation. The dependent (or responding) variable is the one that is observed and likely changes in response to the independent variable.

Identify the variables Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.

Independent Variable is the volume of the object. Dependent Variable is the mass of the object. Control Variables are the material of the object, room temperature, and temperature of the water.

The independent variable is what you change, and the dependent variable is what changes as a result of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

Statistics. In an experiment, the variable manipulated by an experimenter is called an independent variable. The dependent variable is the event expected to change when the independent variable is manipulated.
