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 an independent variable?
It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.
What are independent and dependent variables examples?
For example, if you are measuring how the amount of sunlight affects the growth of a type of plant, the independent variable is the amount of sunlight. You can control how much sunlight each plant gets. The growth is the dependent variable. It is the effect of the amount of sunlight.
What is an example of a dependent variable in psychology?
An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy). In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.

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.
Is gender an independent variable?
An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables).
What is the meaning of dependent variable in psychology?
the outcome that is observed to occur or change after the occurrence or variation of the independent variable in an experiment, or the effect that one wants to predict or explain in correlational research.
What are 2 common examples of independent variable?

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.
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 weight an independent variable?
For example people’s weight (dependent variable) might depend on their height (independent variable). Independent is not a very good term, because you can have several independent variables, and they may not be independent of each other.
Is height independent or dependent?
Consequently, height is the independent variable on the horizontal axis, and weight is the dependent variable on the vertical axis.
How do you choose an independent variable?
The best way to identify dependent and independent variables in research is by putting the variables in the sentence “The Independent variable causes a change in Dependent variable.” What are the different types of Variables in research? Variables are characteristics that take on different values.
Is exercise an independent variable?
