what is the difference between independent and dependent variables in statistics?
153169
The independent and dependent variables may be viewed in terms of cause and effect. ... The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent 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.

In an experiment, the independent variable is the variable that is varied or manipulated by the researcher, and the dependent variable is the response that is measured. An independent variable is the presumed cause, whereas the dependent variable is the presumed effect.

The idea is that one variable is the effect of another variable or, to say it another way, that one variable precedes and/or causes another. The dependent variable is the variable to be explained (the 'effect”). The independent variable is the variable expected to account for (the “cause” of) 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.

A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable.

In an experiment, the independent variable is what the scientist has control over, it is the thing that the scientist gets to decide. The dependent variable is different, it is what the scientist looks at or measures, but does not get to decide.

There are two types of variables, namely independent and dependent variables. The distinction is made on the basis of whether the variable determines the other variable or is determined by another variable. The independent variable is those variables whose value does not depend on any other 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.

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.

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 dependent variable is the variable that is being measured or tested in an experiment. ... In a psychology experiment, researchers are looking at how changes in the independent variable cause changes in the dependent 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.

Remember, an independent variable is the part of the experiment the scientist changes or controls. The dependent variable is the part of the experiment that reacts to the independent variable. ... A constant is the part that doesn't change during the experiment.

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.

An independent variable is the variable you have control over, what you can choose and manipulate. Example: You are interested in how stress affects heart rate in humans. ... A dependent variable is the variable being tested in a scientific experiment. The dependent variable is 'dependent' on the independent variable.

Dependent variables A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. y is often the variable used to represent the dependent variable in an equation.
