15 Independent and Dependent Variable Examples (2024)
Examples of Independent and Dependent Variables. 1. Gatorade and Improved Athletic Performance. A sports medicine researcher has been hired by Gatorade to test the effects of its sports drink on athletic performance. The company wants to claim that when an athlete drinks Gatorade, their performance will improve.
Independent vs. 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. Example: Independent and dependent variables. You design a study to test whether changes in room temperature have an effect on math test scores.
Independent & Dependent Variables (With Examples)
While the independent variable is the " cause ", the dependent variable is the " effect " - or rather, the affected variable. In other words, the dependent variable is the variable that is assumed to change as a result of a change in the independent variable. Keeping with the previous example, let's look at some dependent variables ...
Independent and Dependent Variables Examples
Here are several examples of independent and dependent variables in experiments: In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. You want to know which brand of fertilizer is best for your plants.
Independent and Dependent Variables
In research, a variable is any characteristic, number, or quantity that can be measured or counted in experimental investigations. One is called the dependent variable, and the other is the independent variable. In research, the independent variable is manipulated to observe its effect, while the dependent variable is the measured outcome.
Independent and Dependent Variable Examples
If you write out the variables in a sentence that shows cause and effect, the independent variable causes the effect on the dependent variable. If you have the variables in the wrong order, the sentence won't make sense. Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects ...
Independent and Dependent Variables: Differences & Examples
Independent variables are also known as predictors, factors, treatment variables, explanatory variables, input variables, x-variables, and right-hand variables—because they appear on the right side of the equals sign in a regression equation.In notation, statisticians commonly denote them using Xs. On graphs, analysts place independent variables on the horizontal, or X, axis.
Independent and Dependent Variables
Designation of the dependent and independent variable involves unpacking the research problem in a way that identifies a general cause and effect and classifying these variables as either independent or dependent. The variables should be outlined in the introduction of your paper and explained in more detail in the methods section. There are no ...
Independent and Dependent Variables, Explained With Examples
Independent and Dependent Variables, Explained With Examples. Written by MasterClass. Last updated: Mar 21, 2022 • 4 min read. In experiments that test cause and effect, two types of variables come into play. One is an independent variable and the other is a dependent variable, and together they play an integral role in research design.
Dependent & Independent Variables
Independent and dependent variables in research. In experimental research, a variable refers to the phenomenon, person, or thing that is being measured and observed by the researcher. A researcher conducts a study to see how one variable affects another and make assertions about the relationship between different variables.

Examples of Independent and Dependent Variables in Research Studies. Many research studies have independent and dependent variables, since understanding cause-and-effect between them is a key end ...
Types of Variables in Research & Statistics
Parts of the experiment: Independent vs dependent variables. Experiments are usually designed to find out what effect one variable has on another - in our example, the effect of salt addition on plant growth.. You manipulate the independent variable (the one you think might be the cause) and then measure the dependent variable (the one you think might be the effect) to find out what this ...
Independent vs Dependent Variables: Definitions & Examples
The independent variable is the cause and the dependent variable is the effect, that is, independent variables influence dependent variables. In research, a dependent variable is the outcome of interest of the study and the independent variable is the factor that may influence the outcome. Let's explain this with an independent and dependent ...
Importance of Variables in Stating the Research Objectives
There may be a cause-effect relationship between independent and dependent variables. For example, consider a clinical trial with treatment (iron supplement vs placebo) as the independent variable and hemoglobin level as the dependent variable. In children with anemia, an iron supplement will raise the hemoglobin level to a greater extent ...
The Research Problem/Question
Independent and Dependent Variables ; Glossary of Research Terms ; 1. Choosing a Research Problem. ... A research problem is a definite or clear expression [statement] about an area of concern, a condition to be improved upon, a difficulty to be eliminated, or a troubling question that exists in scholarly literature, in theory, or within ...

Independent and Dependent Variables
Extraneous variables (from Adjei, n.d.) While it is very common to hear the terms independent and dependent variable, extraneous variables are less common, which is surprising because an extraneous variable can destroy the integrity of a research study that claims to show a cause and effect relationship. An extraneous variable is a variable that may compete with the independent variable in ...
4.5 Independent and Dependent Variables
4.5 Independent and Dependent Variables. When one variable causes another variable, we have what researchers call independent and dependent variables. In the example where gender was found to be causally linked to cell phone addiction, gender would be the independent variable (IV) and cell phone addiction would be the dependent variable (DV).

A Practical Guide to Writing Quantitative and Qualitative Research
In quantitative research, hypotheses predict the expected relationships among variables.15 Relationships among variables that can be predicted include 1) between a single dependent variable and a single independent variable (simple hypothesis) or 2) between two or more independent and dependent variables (complex hypothesis).4,11 Hypotheses may ...
Independent vs. Dependent Variables ~ Use & Examples
An independent variable is one that is manipulated by the researcher. A dependent variable is one that is being tested in a research experiment. Scientific research assesses the effect on dependent variables based on the changes in independent variables. This article shows examples of how to illustrate dependent and independent variables in graphs.

Roles of Independent and Dependent Variables in Research
The relationship between independent and dependent variables can manifest in various forms—direct, indirect, linear, nonlinear, and may be moderated or mediated by other variables. At its most basic, this relationship is often conceptualized as cause and effect: the independent variable (the cause) influences the dependent variable (the effect).
