In an experiment the dependent variable (DV) is the variable that the researcher measures. It is the variable that is affected by the manipulation of the independent variable (IV).
What is independent and dependent variable in psychology?
Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
What is an example of a dependent variable in a study?
The dependent variable is the variable that is being measured or tested in an experiment. 1 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.
What is an independent variable in psychology example?
The independent variable is the variable that is manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.
What is the dependent variable in psychology? – Related Questions
What is example of dependent and independent?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
What is the difference between dependent and independent variable?
In analytical health research there are generally two types of variables. Independent variables are what we expect will influence dependent variables. A Dependent variable is what happens as a result of the independent variable.
How do you remember independent and dependent variables?
An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
What are 2 examples of independent variables?
Two examples of common independent variables are age and time. There’s nothing you or anything else can do to speed up or slow down time or increase or decrease age. They’re independent of everything else.
What is an independent variable simply psychology?
An independent variable (IV) is a variable that is manipulated by a researcher to investigate whether it consequently brings change in another variable. This other variable, which is measured and predicted to be dependent upon the IV, is therefore named the dependent variable (DV).
What are some examples of independent and dependent variables and control?
Example: a car going down different surfaces. Independent variable: the surface of the slope rug, bubble wrap and wood. Dependent variable: the time it takes for the car to go down the slope. Controlled variable: the height of the slope, the car, the unit of time e.g. minutes and the length of the slope.
Which of the following is the independent variable psychology?
The independent variable (IV) in psychology is the characteristic of an experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
What is a dependent variable simple?
It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
What is a dependent variable psychology quizlet?
dependent variable. Definition: The research variable that changes or varies as a result of the independent variable.
How do you find the independent and dependent variables?
How do I identify a independent variable?
Is time a dependent variable?
Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.
Is age a dependent variable?
Age is looked at as a dimension along which behavior changes are to be traced, forming part of the definition of the dependent variable in developmental studies.
Why are dependent variables important?
Dependent variables are an important part of conducting research studies. Researchers use the dependent variable to study a hypothesis and further their research. Learning how to identify and choose a dependent variable can help you set up effective studies.
Is temperature independent or dependent?
Temperature is what you manipulate and is not depended on any other factor. That is why you call temperature an independent variable. It is also called manipulated variable.
Is water a dependent variable?
Changing the amount of water affects the value of the plant growth rate. This is how we know that amount of water is the independent variable and plant growth rate is the dependent variable.
