The independent variable is the variable that is manipulated by the experimenter. … The dependent variable is the variable that is measured by the experimenter. In the previous example, the scores on the test performance measure would be the dependent variable.
What is a dependent variables in psychology?
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.
What is independent variable and dependent variable examples?
For example, in an experiment about the effect of nutrients on crop growth: The independent variable is the amount of nutrients added to the crop field. The dependent variable is the biomass of the crops at harvest time.
What is the difference between dependent variable and an independent variable?
The main difference between Independent Variables and Dependent Variables is in the definition. Independent variables in research can be manipulated or altered to see their impact on other variables. The dependent variable is dependent on other variables. It is the variable that is measured or tested by a researcher.
What is the example of a dependent variable?
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 independent variable in psychology?
The independent variable (IV) is the characteristic of a psychology 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.
Which is the independent variable?
The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. … The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.
What is dependent variable in research?
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.
How do you know if two variables are independent or dependent?
You can tell if two random variables are independent by looking at their individual probabilities. If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.
