Understanding and managing extraneous variables is essential for ensuring the validity and reliability of research findings. This article explores the types of extraneous variables, strategies to control them, and practical examples of how they affect research.
Extraneous Variables | Examples, Types & Controls Published on April 2, 2021 by Pritha Bhandari. Revised on January 14, 2025. In an experiment, an extraneous variable is any variable that you’re not investigating that can potentially affect the outcomes of your research study. If left uncontrolled, extraneous variables can lead to inaccurate conclusions about the relationship between ...
A simple explanation of extraneous variables, including a formal definition and several examples.
Examples of extraneous variables include environmental factors, participant characteristics, and random events. For instance, the temperature in a room where a study is being conducted can impact participants’ mood and behavior, thus affecting the results.
In the world of psycholo g ical research, the term “ extraneous variables ” refers to those factors that can interfere with the results of an experiment. These variables may not be the focus of the study, but they have the potential to influence the outcome of an experiment, ultimately complicating the interpretation of the findings. When conducting psychological experiments, researchers ...
An extraneous variable is anything in a psychology experiment other than the independent and dependent variables. The variables can present challenges and introduce errors, so it is important for experiments to control these extraneous factors.
Examples include: An individual’s natural intelligence. An individuals’ mood that day. An individual’s physical abilities. An individual’s ability to concentrate. How to Control Extraneous Variables There are four main ways to control for extraneous variables in an experiment: 1. Consistent environment.
Extraneous variables are factors that can adversely influence study outcomes, leading to skewed results that might be misinterpreted. These variables are not the primary focus of the research but can still interfere with the relationship between the independent and dependent variables.
An extraneous variable is anything that could influence the dependent variable. A confounding variable is an extraneous variable associated with both independent and dependent variables.
An extraneous variable, also known as a confounding variable, is an unpredictable factor that unintentionally affects the relationship between the independent variable and the dependent variable in an experiment.

Confounding variables is one of the extraneous variables. According to its name, the work of the confounding variables is to confuse the true effects of the independent variables across all levels. Because just as the independent variables, confounding variables also differ across the conditions that the researcher may introduce.
What is a confoundin g or extraneous variable? An extraneous variable is one which might interfere with the DV. (These are sometimes referred to as uncontrolled variables) A confounding variable is one which has definitely interfered with the DV, and “confounded” the result.
An extraneous variable is an outside influence that can affect the outcome of an experiment. These variables are not related to the variables being tested, and can cause unexpected results. Therefore, it is important to identify and control for these variables in order to ensure reliable results.
One of the most common types of confounding occurs when an experimenter does not or can not randomly assign participants to groups, and some type of individual difference (e.g., ability, extroversion, shyness, height, weight) acts as a confounding variable. For example, any experiment that involves a comparison of men and women is inherently plagued with confounding variables, the most ...
Extraneous variable (EV) is a general term for any variable, other than the IV, that might affect the results (the DV). Where EVs are important enough to cause a change in the DV, they become confounding variables.
Example 6.2 In the typing-speed study (Example 5.4), potential extraneous variables may include age, the presence or absence of certain medical conditions, the level of familiarity with computers, etc.
An Extraneous Variable is something that the experimenter cannot control, which can have an effect on the overall outcome of the experiment. The main four extraneous variables are demand characteristics, experimenter effects, participant variables and situational variables.
