  1. What Is a Control Variable? Definition and Examples

    Control Variable Examples. Anything you can measure or control that is not the independent variable or dependent variable has potential to be a control variable. Examples of common control variables include: Duration of the experiment. Size and composition of containers. Temperature.

  2. Types of Variables in Science Experiments

    The two key variables in science are the independent and dependent variable, but there are other types of variables that are important. In a science experiment, a variable is any factor, attribute, or value that describes an object or situation and is subject to change. An experiment uses the scientific method to test a hypothesis and establish whether or not there is a cause and effect ...

  3. What Is a Variable in Science? (Types of Variables)

    Independent Variable: The independent variable is the one condition that you change in an experiment. Example: In an experiment measuring the effect of temperature on solubility, the independent variable is temperature. Dependent Variable: The dependent variable is the variable that you measure or observe. The dependent variable gets its name ...

  4. Independent and Dependent Variables Examples

    Example: If you change the color of light (independent variable), then it affects plant growth (dependent variable). Example: If plant growth rate changes, then it affects the color of light. Sometimes you don't control either variable, like when you gather data to see if there is a relationship between two factors.

  5. Types of Variables in Research & Statistics

    In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable. For example, in an experiment about the effect of nutrients on crop growth: The independent variable is the amount of nutrients added to the crop field. The dependent variable is the biomass of the crops at harvest time.

  6. What are Variables?

    Controlled variables are quantities that a scientist wants to remain constant, and she or he must observe them as carefully as the dependent variables. For example, in the dog experiment example, you would need to control how hungry the dogs are at the start of the experiment, the type of food you are feeding them, and whether the food was a ...

  7. What are Variables?

    The dependent variables are the things in an experiment that the scientist observes and measures. Scientists want to know if changing the independent variable has an effect on the dependent variables. In our dog example, the dependent variable is how much the dogs eat. This is what we are watching and measuring.

  8. Independent vs. Dependent Variables

    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. Your independent variable is the temperature ...

  9. Types of Variables in Research

    In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable. For example, in an experiment about the effect of nutrients on crop growth: The independent variable is the amount of nutrients added to the crop field. The dependent variable is the biomass of the crops at harvest time.

  10. Variables in Research: Breaking Down the ...

    These variables are crucial for defining the relationships between factors within an experiment or study and determining the cause-and-effect relationships that underpin scientific knowledge. ... dependent variable is the variable that the researcher expects to change as a result of manipulating the independent variable. Example: In the ...

  11. 9 Types of Experiment Variables

    A situational variable is an aspect of the environment that may influence the experiment. For example, air quality in a health related experiment. Subject Variables ... A confounding variable is a variable that influences both the independent variable and the dependent variable. For example, stress may make people smoke more and also directly ...

  12. Controls & Variables in Science Experiments

    An example of a control in science would be cells that get no treatment in an experiment. Say there is a scientist testing how a new drug causes cells to grow. One group, the experimental group ...

  13. What Are Dependent, Independent & Controlled Variables?

    References. About the Author. In an experiment, there are multiple kinds of variables: independent, dependent and controlled variables. The independent variable is the one the experimenter changes. The dependent variable is what changes in response to the independent variable. Controlled variables are conditions kept the same.

  14. Guide to Experimental Design

    There are five key steps in designing an experiment: Consider your variables and how they are related. Write a specific, testable hypothesis. Design experimental treatments to manipulate your independent variable. Assign subjects to groups, either between-subjects or within-subjects.

  15. Types of Variables in Science Experiments

    All types of variables can affect your science experiment. Get information about independent, dependent, control, intervening, and extraneous variables. ... It is like an adult in that it is free from outside control of the other variables. Examples of independent variables include: In an experiment to see what brand of diapers hold the most ...

  16. Independent and Dependent Variable Examples

    Independent and Dependent Variable Examples. In a study to determine whether the amount of time a student sleeps affects test scores, the independent variable is the amount of time spent sleeping while the dependent variable is the test score. You want to compare brands of paper towels to see which holds the most liquid.

  17. Independent Variable Definition and Examples

    Here are some examples of an independent variable. A scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off. The independent variable is the amount of light (cause) and the moth's reaction is the dependent variable (the effect). In a study to determine the effect of temperature on plant ...

  18. 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.

  19. Independent vs. Dependent Variables: What's the Difference?

    by Zach Bobbitt February 5, 2020. In an experiment, there are two main variables: The independent variable: the variable that an experimenter changes or controls so that they can observe the effects on the dependent variable. The dependent variable: the variable being measured in an experiment that is "dependent" on the independent variable.
