If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5.
Similarly, 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. … In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
Additionally, How do you identify the dependent variable? 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 are some examples of independent and dependent variables?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
How do you find an independent variable?
Answer: An independent variable is exactly what it sounds like. 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.
What is the independent variable example?
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 the independent variable of the experiment?
Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.
What is an independent variable in a study?
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.
How do you identify variables in research?
A variable in research simply refers to a person, place, thing, or phenomenon that you are trying to measure in some way. The best way to understand the difference between a dependent and independent variable is that the meaning of each is implied by what the words tell us about the variable you are using.
What is the independent and dependent variable in an experiment?
Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.
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 are the 3 types of variables?
There are three main variables: independent variable, dependent variable and controlled variables. Example: a car going down different surfaces.
What is the independent variable for this experiment?
Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.
What is the independent variable in this experiment?
An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.
What is the dependent variable in an experiment example?
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.
How do I find the independent variable?
You can also think of the independent variable as the cause and the dependent variable as the effect. When graphing these variables, the independent variable should go on the x-axis (the horizontal axis), and the dependent variable goes on the y-axis (vertical axis).
What is independent and dependent variable in Research example?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
What are some examples of independent and dependent variables in research?
The dependent variable is the effect. Its value depends on changes in the independent variable.
…

How do you identify the independent and dependent variables in a research study?
The variables in a study of a cause-and-effect relationship are called the independent and dependent variables.
- 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 examples of variables in research?
Categorical variables
| Type of variable | What does the data represent? | Examples |
|---|---|---|
| Nominal variables | Groups with no rank or order between them. | Species names Colors Brands |
| Ordinal variables | Groups that are ranked in a specific order. | Finishing place in a race Rating scale responses in a survey* |

What are the types of variables in research?
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.
How do we classify variables?
Classifying variables can be somewhat contentious. Standard statistical textbooks will state that variables can be broadly classified as categorical or continuous. Categorical variables can be further categorised into nominal (e.g. ethnic group), ordinal (e.g. tumour staging) and dichotomous (e.g. sex).
What are the 3 types of variables in an experiment?
There should be three categories of variables in every experiment: dependent, independent, and controlled. Dependent — is what will be measured; it’s what the investigator thinks will be affected during the experiment.
What are the 3 variables in science?
There are three main variables: independent variable, dependent variable and controlled variables.
