What variables affect dependent variables?
One way to help identify the dependent variable is to remember that it depends on the independent variable. When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable.
How do you choose a dependent variable?
You can also think of the independent variable as the cause and the dependent variable as the effect. When graphing these variables, the independent variable should go on the x-axis (the horizontal axis), and the dependent variable goes on the y-axis (vertical axis).
Which of the best describe dependent variables?
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.
Can a study have more than one dependent variable?
It is also important to remember that while some studies may only have one dependent variable and one independent variable, it is also possible to have several of each type of variable. For example, researchers might want to learn how variables in a single independent variable affect several distinct dependent variables.
Which is the best definition of a dependent variable?
Definitions. Dependent Variable. The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables. It is the presumed effect. Independent Variable.
How are test scores dependent on independent variables?
The test scores vary based on the amount of studying prior to the test. The researcher could change the independent variable by instead evaluating how age or gender influence test scores. How does stress influence memory?
When do researchers make changes to the independent variable?
When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable. For example, if a researcher was looking at how studying influences test scores, the amount of studying would be the independent variable and the test scores would be the dependent variable.
