dependent and independent variable what does it mean?

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.

Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. ... Any change in a controlled variable would invalidate the results.

An independent variable is a variable that represents a quantity that is being manipulated in an experiment. In the context of a function, the independent variables are the inputs to the function and the dependent variables are the outputs of the function. ...

An independent variable is a variable that is manipulated to determine the value of a dependent variable. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation and the independent variables are the inputs to that measurement.

The dependent variable is the variable that is being measured or tested in an experiment. ... When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable.

Definitions. In an experiment, the independent variable is the variable that is varied or manipulated by the researcher. The dependent variable is the response that is measured. ... Here the independent variable is the dose and the dependent variable is the frequency/intensity of symptoms.

The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. ... The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable.

Independent variable is the quantity that the Chemist causes to change. Dependent variable is the quantity that responds to the change the Chemist has caused.

An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables).

A DEPENDENT VARIABLE is "something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

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.

The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable. An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy).

The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable. ... In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.

An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.

An independent variable is a variable that represents a quantity that is being manipulated in an experiment. A dependent variable represents a quantity whose value depends on those manipulations.

A dependent variable is the variable being tested in a scientific experiment. The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.

You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.
