Learn the definitions and key differences between independent and dependent variables, along with their uses in research, data science, and machine learning, with clear examples.
Independent and Dependent Variables | Difference & Examples Published on October 2, 2024 by Emily Heffernan, PhD Revised on December 16, 2024 In an experiment, a researcher tests a hypothesis by manipulating an independent variable and measuring its impact on a dependent variable. A variable is any property that can take on different values (e.g., height, temperature, GPA). Experiments test ...
Variables are an important concept in experimental and hypothesis-testing research, so understanding independent/dependent variables is key to understanding research design. In this article, we will talk about what separates a dependent variable from an independent variable and how the concept applies to research.
Independent variables and dependent variables are the two fundamental types of variables in statistical modeling and experimental designs.
Variables in research and statistics are of different types—independent, dependent, quantitative (discrete or continuous), qualitative (nominal/categorical, ordinal), intervening, moderating, extraneous, confounding, control, and composite. In this article we compare the first two types—independent vs dependent variables.
Independent Variables The Independent variable is a type of variable used in experimental sciences, statistical modeling, and mathematical modeling which doesn’t depend on any other variables in the scope of the experiment. An independent variable can be manipulated in an experiment, which in turn affects the changes in the dependent variables. Mostly in mathematical equations, independent ...

Reviewing independent and dependent variable examples can be the key to grasping what makes these concepts different. Explore these simple explanations here.
Independent variables, dependent variables, confounding variables – it’s a lot of jargon. In this post, we’ll unpack the terminology surrounding research variables using straightforward language and loads of examples.
Learn the meaning, types, and differences between independent and dependent variables. We’ve also added independent and dependent variable examples.
The dependent variable, in both cases, is what is being observed or studied to see how it changes in response to the independent variable. So, regardless of the type of data, researchers analyze the relationship between independent and dependent variables to gain insights into their research questions.
Independent versus dependent variables: This guide will explain these concepts, provide real-world examples, and offer tips for utilizing them in research.
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.
The variables in question can be from any of the scales of measure from chapter 6. Take the smoking example, with patients as the object of study. We might say that independent variable A is categorical, with values SMOKER and NON-SMOKER. The dependent variable B is also categorical: CANCER and NO-CANCER.
