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 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 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 are the 6 types of independent variables?
Independent Variables: Other Names and Uses.
- A controlled variable.
- An explanatory variable.
- An exposure variable (in reliability theory).
- A feature (in machine learning and pattern recognition).
- An input variable.
- A manipulated variable.
- A predictor variable.
- A regressor (in regression analysis).
What is an example of an independent variable? – Related Questions
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.
What are 4 examples of variables?

What are the 6 variables in research?

Can you have 4 independent variables?
In practice, it is unusual for there to be more than three independent variables with more than two or three levels each. This is for at least two reasons: For one, the number of conditions can quickly become unmanageable.
How many independent variables are there?
Answer and Explanation: You can have as many independent variables in an experiment, as you want, but you would like to design your experiments to have only one independent variable if it is possible. This is because it allows you to determine whether your independent variable influences your dependent variable.
How do you know if two variables are independent?
Intuitively, two random variables X and Y are independent if knowing the value of one of them does not change the probabilities for the other one. In other words, if X and Y are independent, we can write P(Y=y|X=x)=P(Y=y), for all x,y.
How do you identify the 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.
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).
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 happiness a independent variable?
The dependent variable is the happiness level and independent variables include interaction terms between After disaster and Trust (fixed effects estimation) The positive relationship between trust and happiness has been demonstrated by the literature.
Is heart rate an independent variable?
The dependent variable is your heart rate, because your heart rate depends on how fast you’re walking. That’s the outcome you want to measure in your experiment.
Is anxiety a dependent or independent variable?
Anxiety is the dependent variable, exam performance is the independent variable.
Is stress an independent variable?
Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.
Is depression an independent or dependent variable?
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.
Is pain an independent or dependent variable?
The change in pain level is the dependent variable; it depends on the treatment.
