what is the dependent variable in a science experiment?
50178
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).

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.

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.

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.

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.

dependent variable. A factor or phenomenon that is changed by the effect of an associated factor or phenomenon called the independent variable. For example, consumption is a dependent variable because it is caused and influenced by another variable: income.

The independent variable is what is in the experimenters' control and the experimenter explicitly manipulates it. The dependent variable is the numerical measure of what the outcome of the manipulation should be: the data that the experimenter gathers.

By. skynesher / Getty Images. The dependent variable is the variable that is being measured or tested in an experiment. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured.

The dependent variable is the variable a researcher is interested in. The changes to the dependent variable are what the researcher is trying to measure with all their fancy techniques. ... An independent variable is a variable believed to affect the dependent 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.

An experiment examines the effects of independent variable on a dependent variable. The independent variable takes the form of an experimental stimulus which is either present or absent. The experimenter compares what happens when the stimulus is present to what happens when it is not.

An independent variable is a quantity that is directly controlled by the observer or experimenter. The dependent variable, as its name suggests, depends on the independent variable. The dependent variable is often the quantity you want to measure; it the result of the experiment or test.

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.

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 experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.
