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.

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.

The Dependent and Independent Variables The independent variable is the variable that is controlled and manipulated by the experimenter. ... The dependent variable is the variable that is measured by the experimenter. In our previous example, the scores on the test performance measure would be the 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 dependent variable is 'dependent' on the independent variable.

Nursing 360: Independent Variable VS Dependent Variable In an experiment, the independent variable is the variable that is varied or manipulated by the researcher. ... Here the independent variable is the dose and the dependent variable is the frequency/intensity of symptoms.

In research design, independent variables are those that a researcher can manipulate, whereas dependent variables are the responses to the effects of independent variables.

Independent variable – the variable that is altered during a scientific experiment. ... Controlled variable – a variable that is kept the same during a scientific experiment. Any change in a controlled variable would invalidate the results.

The dependent variable is the one that depends on the value of some other number. ... Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5.

' A variable is defined as anything that has a quantity or quality that varies. The dependent variable is the variable a researcher is interested in. An independent variable is a variable believed to affect the dependent variable. Confounding variables are defined as interference caused by another variable.

The "independent variable" is the one that you think of as causal, the "dependent variable" is the one that you think of as being affected by the "independent variable." ... The way the terms "independent variable" and "dependent variable" are used these days causes much confusion and some mischief.

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.

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.

A dependent variable represents a quantity whose value depends on those manipulations. 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.
