What Is a Variable in Science? (Types of Variables)
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.
What are Variables?
In science, a variable is anything that can change or be different. It can be a thing (like a shirt or a jacket), a characteristic (like rough or smooth), or a situation (like sunny or cloudy). Scientists want to know how things work. They want to understand why things happen and use that information to predict what will happen in the future.
Variables
During experiments, factors that can change are called variables. A variable is anything that can change and be measured. Two important types of variables are: Independent variables - the ...
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 ...
Independent and Dependent Variables Examples
The dependent variable is the factor that changes in response to the independent variable. It is the variable that you measure in an experiment. The dependent variable may be called the "responding variable." Examples of Independent and Dependent Variables. Here are several examples of independent and dependent variables in experiments:
Variables in Research: Breaking Down the Essentials of Experimental
The Role of Variables in Research. In scientific research, variables serve several key functions: Define Relationships: Variables allow researchers to investigate the relationships between different factors and characteristics, providing insights into the underlying mechanisms that drive phenomena and outcomes. Establish Comparisons: By manipulating and comparing variables, scientists can ...
What are Variables?
In science, a variable is any factor, trait, or condition that can exist in differing amounts or types. Scientists try to figure out how the natural world works.To do this they use experiments to search for cause and effect relationships. Cause and effect relationships explain why things happen and allow you to reliably predict the outcomes of ...
Controlled experiments (article)
For example, you might want to see how water and light levels jointly affect bean seed sprouting. A well-designed experiment with two independent variables can tell you whether the variables interact (modify each other's effects). However, experiments with more than one independent variable have to follow specific design guidelines, and the ...
What Is a Control Variable? Definition and Examples
A control variable is any factor that is controlled or held constant during an experiment. For this reason, it's also known as a controlled variable or a constant variable. ... Remember, the independent variable is the one you change, the dependent variable is the one you measure in response to this change, and the control variables are any ...
Definitions of Control, Constant, Independent and Dependent Variables
The point of an experiment is to help define the cause and effect relationships between components of a natural process or reaction. The factors that can change value during an experiment or between experiments, such as water temperature, are called scientific variables, while those that stay the same, such as acceleration due to gravity at a certain location, are called constants.
9 Types of Experiment Variables
Variables are factors that influence an experiment or that are of interest as a result. These include variables you change to test a hypothesis, variables you measure to determine results and variables you hold constant to produce a valid experiment. The following are the basic types of variable that are relevant to experiments.
What is a Manipulated Variable? (Definition & Example)
An experiment is a controlled scientific study. In statistics, we often conduct experiments to understand how changing one variable affects another variable. A manipulated variable is a variable that we change or "manipulate" to see how that change affects some other variable. A manipulated variable is also sometimes called an independent variable.. A response variable is the variable that ...
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.

Science Terms and Definitions You Should Know
Control Variable: Any variable that does not change during an experiment. Also known as a constant variable. Data (singular: datum): Facts, numbers, or values obtained in an experiment. Dependent Variable: The variable that responds to the independent variable. The dependent variable is the one being measured in the experiment.
PDF Variables in Your Science Fair Project
An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens.
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.
The Basics of an Experiment
The independent variable is the one factor that you are changing. It is one factor because usually in an experiment you try to change one thing at a time. This makes measurements and interpretation of the data much easier. If you are trying to determine whether heating water allows you to dissolve more sugar in the water then your independent variable is the temperature of the water.
UCSB Science Line
In an experiment, independent variables are the quantities you change in order to change other quantities. For instance, if you were doing an experiment in which you want to find out how the number of hours of sunlight exposure affects plant growth, you might have two variables: number of hours of sunlight given to the plant per day, and the ...
Manipulated Variable
In a controlled scientific experiment, a variable is a factor that changes. There are multiple types of variables in an experiment. The definition of a manipulated variable is a factor that is ...
Identify Variables in a Scientific Investigation
Control variable - these are the elements that are kept the same during a scientific experiment. There can be multiple control variables. Any change to a controlled variable would invalidate the results, so it's really important that they are kept the same throughout. So, using our example, we now should be able to identify the variables ...
Independent and Dependent Variables: Which Is Which?
There are two key variables in every experiment: the independent variable and the dependent variable. Independent variable: What the scientist changes or what changes on its own. Dependent variable: What is being studied/measured. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected ...
What Is an Experimental Constant?
B2M Productions, Getty Images. A constant is a quantity that does not change. Although you can measure a constant, you either cannot alter it during an experiment or else you choose not to change it. Contrast this with an experimental variable, which is the part of an experiment that you change or that is affected by the experiment.
