What Are Some Examples Of Independent And Dependent Variables

They could however be graphed as a verification that other conditions are not changing.

For example in an experiment about the effect of nutrients on crop growth. The dependent variable is the biomass of the crops at harvest time. The dependent varible is defined as the thing which is being measured in an experiment whilst the independent variable is the thing that is being manipulated or changed. Dependent variable a person s financial net worth.

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. The dependent variable which changes in response to the independent variable is graphed on the y axis. 5 an electric motor rotates faster by increasing the voltage.

To investigate factor related to income source of a community income is dv and factors like expenditure family size location rural or urban all are iv. In an experiment you manipulate the independent variable and measure the outcome in the dependent variable. Independent variable iv and dependent variable dv depends on researcher choice of interest. An example of a dependent variable is depression symptoms which depends on the independent variable type of therapy.

Independent variable iv what the experimenter manipulates to see if it affects behavior. You are studying the effects of alcohol on memory. Independent variable a person s country of origin. The independent variable is graphed on the x axis.

Rotation speed measured in revolutions per minute dependent variable. The amount of alcohol is the iv and you are measuring the memory dv. The dependent variable is the variable being tested and measured in an experiment and is dependent on the independent variable. A social scientist wonders if there is an association between a person s national origin and their wealth measured as net worth.

Dependent variable dv the behavior that is measured to see if the iv had an effect. It s what changes as a result of the changes to the independent variable. Extraneous variables are undesirable variables that influence the relationship between the variables that the experimenter is observing. Independent and dependent variable examples in a study to determine whether how long a student sleeps affects test scores the independent variable is the length of time spent sleeping while the dependent variable is the test score.

An example of a dependent variable is how tall you are at different ages. National origin and net worth. The dependent variable would be the flow of water measured in liters per minute. Controlled variables are usually not graphed because they should not change.
