What is an example of a dependent variable in psychology?
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 the independent variable in a psychology experiment?
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.
What is my independent and dependent 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.
Is temperature independent variable?
An independent variable is one that is unaffected by changes in the dependent variable. For example when examining the influence of temperature on photosynthesis, temperature is the independent variable because it does not dependent upon photosynthetic rate. For example, photosynthesis is dependent upon temperature.
What is the difference between independent and dependent variable examples?
A dependent variable depends on an independent variable, while an independent variable depends on external manipulation. For example, when measuring how the speed of a car will affect the time it will take to reach a certain place, the time taken (dependent variable) depends on the speed (independent variable).
What is the difference between independent and dependent variable in psychology?
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.
Is rainfall dependent or independent?
Rainfall depends on time of year, but time of year does not depend on rainfall. Therefore, rainfall is the dependent variable and time of year is the independent variable. In some graphs, you may have more than one dependent variable, but never more than one independent variable.
Is sunlight independent or dependent?
In this case, the number of hours of sunlight is the independent variable and the height of the plant is the dependent variable, because the change in the height depends on the hours of sunlight, not the other way around.
How do you remember the difference between independent and dependent variables?
An easy way to remember the difference between independent and dependent variables is to insert the two variables into the following sentence in such a way that it makes sense: What is this? Changing (independent variable) affects the value of (dependent variable).
What are dependent random variables?
Two random variables are called “dependent” if the probability of events associated with one variable influence the distribution of probabilities of the other variable, and vice-versa. In other words, there exist events and containing outcomes of and , respectively, such that Pr(A and B) is not equal to .
