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 are independent and dependent variables 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 some examples of independent and dependent variables in psychology?
Let’s take the example of “Test Scores”. You want to see the effect of studying or sleeping on a test score. In the example, “test score” is the dependent variable. “Studying” or “sleeping” is the independent variable because these factors impact how much a student scores on the test.
What are the 3 types of variables in psychology?
There are three main variables: independent variable, dependent variable and controlled variables.
What is an independent variable in psychology example? – Related Questions
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.
How do you identify independent dependent and control variables?
Identify the variables
Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.
What are 3 important controlled variables?
Examples of control variables
- Temperature.
- Amount of light.
- Amount of water.
What are the 3 variables that can be used in research topic?
Researchers organize variables into a variety of categories, the most common of which include:
- Independent variables.
- Dependent variables.
- Intervening variables.
- Moderating variables.
- Control variables.
- Extraneous variables.
- Quantitative variables.
- Qualitative variables.
What are 3 controlled variables in an experiment?
Examples of Controlled Variables
If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment.
What are key variables in psychology?
The key variables are the terms to be operationally defined if an Operational Definition of Terms section is necessary. The key variables provide focus to the Methods section. The Instrument will measure the key variables. These key variables must be directly measured or manipulated for the research study to be valid.
Is time an independent variable?
The independent variable is the variable that is controlled throughout the experiment, but it is not affected by any other variable. So, like its name suggests, it is independent from other variables. Time, for example, will always be an independent variable.
What are the five psychological variables?

- i. Motivation. When a person is motivated enough, it influences the buying behavior of the person.

What are examples of Dependant variables?
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 the independent variable in an experiment?
The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.
What are examples of variables in a research study?
It could be demographic, physical or social and include religion, income, occupation, temperature, humidity, language, food, fashion, etc. Some variables can be quite concrete and clear, such as gender, birth order, types of blood group etc while others can be considerably more abstract and vague.
Is pain an independent variable?
The dose is the independent variable; it is controlled to be the same on all patients in the experiment and is therefore independent of the patients’ response. The change in pain level is the dependent variable; it depends on the treatment.
How do you write an independent and dependent variable in a hypothesis?
The hypothesis is often written using the words “IF” and “THEN.” For example, “If I do not study, then I will fail the test.” The “if’ and “then” statements reflect your independent and dependent variables. The hypothesis should relate back to your original question and must be testable.
How do you identify variables in a research paper?
The variables should be outlined in the introduction of your paper and explained in more detail in the methods section. There are no rules about the structure and style for writing about independent or dependent variables but, as with any academic writing, clarity and being succinct is most important.
How many independent variables should there be in an experiment?
To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect. The dependent variable is the item that responds to the change of the independent variable.
