What is the difference between an independent variable and a dependent variable?
KEY DIFFERENCES:
- An Independent variable is a variable whose value never depends on another variable whereas a dependent variable is a variable whose value depends on another variable.
- The Independent variable is the presumed cause. ...
- Independent variables are the predictors or regressors but dependent variables are often referred as the predicted variable.
What is an example of independent variable in research?
The following are illustrative examples of independent variables. Changing the amount of fertilizer given to plants as an independent variable. In this experiment, dependent variables might be plant height and weight. Control variables might include water, sunlight and soil. Giving medication to one group and a placebo to another.
What are some examples of dependent and independent variables?
Here are several examples of independent and dependent variables in experiments:

And the scientist knows the independent variable before the experiment is run the dependent variable is the variable. That may or may not change.
How do you identify the dependent variable in a study?
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 you determine independent and dependent variables examples?
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. This doesn't really make sense (unless you can't sleep because you are worried you failed a test, but that would be a different experiment).
How would you identify the 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.
How do you identify variables in a research study?
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 independent variable in research example?
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.
Identifying Independent and Dependent Variables
Even though the definitions of the terms independent and dependent variables may appear to be clear, in the process of analyzing data resulting from actual research, identifying the variables properly might be challenging.
Writing Style and Structure
Usually, the variables are first described in the introduction of a research paper and then in the method section. No strict guidelines for approaching the subject exist; however, academic writing demands that the researcher make clear and concise statements.
Conclusion
In properly organizing a research paper, it is essential to outline and operationalize the appropriate independent and dependent variables. Moreover, the paper should differentiate clearly between independent and dependent variables.
What is dependent variable in social science?
Don't feel bad if you are confused about what is the dependent variable and what is the independent variable in social and behavioral sciences research. However, it's important that you learn the difference because framing a study using these variables is a common approach to organizing the elements of a social sciences research study in order to discover relevant and meaningful results. Specifically, it is important for these two reasons: 1 You need to understand and be able to evaluate their application in other people's research. 2 You need to apply them correctly in your own research.

Why is it important to learn the difference between framing and using variables?
However, it's important that you learn the difference because framing a study using these variables is a common approach to organizing the elements of a social sciences research study in order to discover relevant and meaningful results.
Where should variables be outlined in a 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.
What are the methods of analysis in social and behavioral science?
Techniques include associations, sampling, random selection, and blind selection .
How to measure dependent variable?
Draw dashes along the y-axis to measure the dependent variable. As with the x-axis, make dashes along the y-axis to divide it into units. If you're studying the effects of advertising on your apple sales, the y-axis measures how many apples you sold per month.
What is an independent variable?
An independent variable stands alone and isn’t affected by other variables. In a scientific experiment, a researcher changes an independent variable to see how it affects other variables. For example, if a researcher wants to see how well different doses of a medication work, the dose is the independent variable.
What is the goal of an experiment or study?
The goal of an experiment or study is to explain or predict the dependent variables caused by the independent variable. Say a researcher is testing an allergy medication. Allergy relief after taking the dose is the dependent variable, or the outcome caused by taking the medicine.
Do dots affect the dependent variable?
The independent variable probably doesn’t affect the dependent variable if the dots are randomly scattered across the graph without any recognizable order.
Can a dependent variable change an independent variable?
Remember that a dependent variable can’t change an independent variable. When distinguishing between variables, ask yourself if it makes sense to say one leads to the other. Since a dependent variable is an outcome, it can’t cause or change 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 is dependent and independent variable in a research topic?
A variable is defined as anything that has a quantity or quality that varies. The dependent variable is the variable a researcher is interested in. An independent variable is a variable believed to affect the dependent variable. Confounding variables are defined as interference caused by another variable.
How do you identify variables?
Variables are the factors in a experiment that change or potentially change. There are two types of variables independent and dependent, these variables can also be viewed as the cause and effect of an experiment.
What is the best definition of dependent variable?
a variable in a functional relation whose value is determined by the values assumed by other variables in the relation, as y in the relation y = 3×2. (in an experiment) the event studied and expected to change when the independent variable is changed.
Is money independent or dependent?
The independent variable is the number of boxes of cookies you buy. The dependent variable is the amount of money you spend on the cookies. The independent variable is the amount of money you spend on the cookies.
How to tell if a variable is independent or dependent?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable. For example, in an experiment about the effect ...
What are dependent variables?
Dependent variables are also known by these terms: Response variables (they respond to a change in another variable) Outcome variables (they represent the outcome you want to measure) Left-hand-side variables (they appear on the left-hand side of a regression equation)
What are the variables in a cause and effect relationship?
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 is the norm for graphing?
The norm is to place the independent variable on the “x”or horizontal axis and the dependent variable on the “y” or vertical axis.
How many levels of a drug can you apply to determine if the independent variable has an effect?
You can apply just two levels (e.g. the new medication and the placebo) in order to find out if the independent variable has an effect at all. You can also apply multiple levels (e.g. three different doses of the new medication) to find out how the independent variable affects the dependent variable.
How to test if a new medication is effective?
To test whether the medication is effective, you divide your patients into two groups. One group takes the medication, while the other group takes a sugar pill placebo.
What are variables in research?
In research, variables are any characteristics that can take on different values, such as height, age, species, or exam score . In scientific research, we often want to study the effect of one variable on another one. For example, you might want to test whether students who spend more time studying get better exam scores.
What are variables in research studies?
A variable in a research study is something or someone you are trying to measure. Variable data can change during a study, allowing for assessment of the conditions leading to the change or the results.
What is an independent variable?
An independent variable is one that is not affected by changes to other variables in a research study. While the independent variable may change during a study, these changes often occur because of the actions of the researchers, or from outside factors unrelated to other variables within the study.
What is a dependent variable?
A dependent variable is one that changes because of changes to another variable in the research study. The results or values of the variable depend on the results or values of a different variable. For example, because water levels can affect plant growth, growth rates are a dependent variable in relation to rainfall levels.
Identifying independent and dependent variables
It's important to identify the dependent and independent variables in a research study. If you are unsure if a variable is dependent or not, these tips can help you make the determination:
Examples of independent and dependent variables in research studies
Here are some examples that show the use of dependent and independent variables across a range of professions to help you better understand the differences and how researchers use them to reach conclusions:
What are the two types of variables in health research?
In analytical health research there are generally two types of variables. Independent variables are what we expect will influence dependent variables. A Dependent variable is what happens as a result of the independent variable.
What is a confounding variable?
A confounding variable, or confounder, affects the relationship between the independent and dependent variables. A confounding variable in the example of car exhaust and asthma would be differential exposure to other factors that increase respiratory issues, like cigarette smoke or particulates from factories.
What is systematic error in study design, subject recruitment, data collection, or analysis that results in a mistaken estimate
Bias is a systematic error in study design, subject recruitment, data collection, or analysis that results in a mistaken estimate of the true population parameter. [2] Although there are many types of bias, two common types are selection bias and information bias.
