In an experiment what is a variable? Confidence votes 2.3K. A variable in an experiment is a quantity or an attribute whose value may vary over the course of an experiment. There are independent and dependent variables. The independent variable is the one being manipulated by an experimenter.

What are Continuous Variables? The variable that is manipulated by the scientist is the independent variable, while the dependent variable is the one that responds to the change. In other words, the response of one variable is dependent on the changes to the other variable.

What is a control in science terms? controlled variable is the sample that stays the same in everybody's experiment. the variable is what is in the experiment. the tested variable is what you test or what you have different from everybody else. Source(s): science class hope this helps yall have fun with science.

The Measure of Mind - Chapter 2 Intro to Psychology In an experimental research design, the variables of interest are called the independent variables and the dependent variables. The independent variableIn an experiment, the variable that is manipulated by the researcher.

- Definition: An independent variable is the variable that is changed or controlled in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable.

- These changing quantities are called variables, and an experiment usually has three kinds: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. In an experiment there is only one independent variable. As the scientist changes the independent variable, he or she observes what happens. The dependent variable changes in response to the change the scientist makes to the independent variable. The new value of the dependent variable is caused by and depends on the value of the independent variable. (the independent variable), the quantity of water flowing (dependent variable) changes in response--the water flow increases. The number of dependent variables in an experiment varies, but there is often more than one.

Control variable A variable in an experiment which is held constant in order to assess the relationship between two other variables, is the control variable. variable in an experiment which is held constant in order to assess the relationship between two other variables, is the control variable.

- These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed/controlled by the scientist.To ensure a fair test, a good experiment has only one independent variable.or example, if you open a faucet part way (the independent variable), the quantity of water flowing (dependent variable) changes in response--you observe that the water flow increases. Experiments also have constants or controlled variables.

What Is the Difference Between the Dependent Variable, the Independent Variable and the Controlled Variable? The dependent variable is the item under observation, the independent variable receives manipulation by a researcher and the control variable is an aspect that affects the dependent variable if the researcher does not hold it constant, explains Nuffield Foundation. These variables form the basis of an experiment or observation. Continue Reading.

Types of Variable All experiments examine some kind of variable(s). A variable is not only something that we measure, but also something that we can manipulate and something we can control for. To understand the characteristics of variables and how we use them in research, this guide is divided into three main sections.

- The Dependent and Independent Variables. In a psychology experiment: The independent variable is the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.

The Parts of a Science Project 1 An experiment can only have one variable. 2  That is, you can change only one condition in each experiment. 3  For example, with the seed experiment, the variable is the temperature at which the seeds are kept before you plant them. An experiment can only have one variable. 2  That is, you can change only one condition in each experiment. 3  For example, with the seed experiment, the variable is the temperature at which the seeds are kept before you plant them.

Independent Variable Definition and Examples The independent variable is one changed in an experiment to test effects on the dependent variable. American Images Inc/Photodisc/Getty Images. Definition: An independent variable is the variable that is changed or controlled in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable. The effect on the dependent variable is measured and recorded. Common Misspellings: independant variable.

What Is a Scientific Variable? Independent Variable. The independent variable is the one factor that you purposely change in an experiment. For example, in an experiment looking at whether plant growth is affected by watering with water or milk the independent variable is the substance used to water the plants.

- A variable the researcher holds constant in an experiment is a controlled factor or constant. All variables remain constant in a controlled experiment except for the one tested and its effects.... A variable the researcher holds constant in an experiment is a controlled factor or constant.

- They are called variables, and there are three forms. The dependent variable is the result of the experiment or function. The independent variable is the one that is deliber … ately changed to observe the effect on the dependent variable.The controlled variables should be maintained constant during the experiment so as not to influence the result.f there is a factor that confuses the result of an experiment, I would call that a design flaw in the experiment. It might also be an uncontrolled variable.

In an experiment what is a variable? The dependent variable is the the variable upon which the effects of manipulating the independent variable are seen/observed. Example: Independent variable-number of daily calories Dependent variable-weight In an experiment, one may wish to examine the effect of the number of daily calories on weight.

Independent, Dependent and Extraneous A variable is anything that can vary, i.e. changed or be changed, such as memory, attention, time taken to perform a task, etc. Variable are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable. • Independent variable (IV) : Variable the experimenter manipulates (i.e. changes) – assumed to have a direct effect on the dependent variable. • Dependent variable (DV) : Variable the experimenter measures, after making changes to the IV that are assumed to affect the DV. For example, we might change the type of information (e.g. organized or random) given to participants to see what effect this might have on the amount of information remembered.

Independent and Dependent Variables Independent Variables are changes that occur in an experiment that are directly caused by the experimenter (you.) Dependent Variables are changes that occur due to independent variables. A Controlled Variable is anything else that could influence the dependent variables.

- Example: If you are studying how salt affects boiling temperature, then salt is the experimental variable. By only changing the salt you will be able to learn how it works. Variables in Experiments —Experiments demand control. If more than one variable changes at a time, the cause and effect is unclear.
