Dependent Variable Definition and Examples Dependent Variable Definition: A dependent variable is the variable being tested in a scientific experiment. The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.

dependent variable dependent variable, (in research) a factor that is measured to learn the effect of one or more independent variables. For example, in a study of the effect of preoperative nursing intervention on postoperative vomiting, vomiting is the dependent variable measured to determine the effect of the nursing intervention.

Variables in Your Science Fair Project The dependent variables are the things that the scientist focuses his or her observations on to see how they respond to the change made to the independent variable. In our dog example, the dependent variable is how much the dogs eat. This is what we are observing and measuring. It is called the dependent variable because we are trying to figure out whether its value depends on the value of the independent variable. If there is a direct link between the two types of variables (independent and dependent) then you may be uncovering a cause and effect relationship. The number of dependent variables in an experiment varies, but there can be more than one. Experiments also have controlled variables. Controlled variables are quantities that a scientist wants to remain constant, and she must observe them as carefully as the dependent variables.

Variable (mathematics) Therefore, in a formula, a dependent variable is a variable that is implicitly a function of another (or several other) variables. An independent variable is a variable that is not dependent. The property of a variable to be dependent or independent depends often of the point of view and is not intrinsic. For example, in the notation f(x, y, z) , the three variables may be all independent and the notation represents a function of three variables.

variable variable, independent, n the variable being studied that is manipulated or controlled by an experimenter. In a drug study an investigator may give several doses of a drug (independent variable) to determine the most effective, symptom-reducing (dependent variable) level.

What Is a Variable in Science? The dependent variable is the variable that you measure or observe. The dependent variable gets its name because it is the factor that is dependent on the state of the independent variable. Example: In the experiment measuring the effect of temperature on solubility, solubility would be the dependent variable.

Dependent variable Learn how you can help Wikiversity to expand it. A dependent variable is used in statistics as the outcome variable which one attempts to predict or explain using one or more independent variables. For example, age of death could be a dependent variable, and gender and current age might be used as independent variables to predict it. Dependent variable (Wikipedia)

Independent Variable Definition and Examples The independent variable is the amount of light and the moth's reaction is the dependent variable. A change in the independent variable (amount of light) directly causes a change in the dependent variable (moth behavior).

Science A variable that we purposefully change or manipulate is called the independent variable. The thing that changes in response is called the dependent variable. This creates a cause and effect relationship. To have a fair test, always have only one independent variable at a time in your investigation.

- The answer is 16. We assume you are converting between ounce and pound. You can view more details on each measurement unit: oz or pounds. The SI base unit for mass is the kilogram. 1 kilogram is equal to 35.2739619496 oz, or 2.20462262185 pounds.

- Independent and Dependent Variables: An independent variable is the variable you have control over, what you can choose and manipulate. It is usually what you think will affect the dependent variable. In some cases, you may not be able to manipulate the independent variable.

Dependent Variable Definition and Examples The type of fertilizer is the independent variable. The rate of growth is the dependent variable. So, to perform an experiment, you would fertilize plants with one fertilizer and measure the change in height of the plant over time, then switch fertilizers and measure the height of plants over the same span of time.

- The dependent variable is the one that is measured by the experimenter. For example, if a researcher wanted to study the effects of fertilizer on plant growth, the independent variable would be the amount of fertilizer and the dependent variable would be the height of the plant.

- To the south and west lie the picturesque Beartooth Mountains whose lofty peaks include Montana’s highest, Granite Peak with an elevation of 12,799 feet. Flowing from the mountains, the Clark’s Fork of the Yellowstone River meanders through central portions of the county.

Dependent Variable vs. Independent Variable in Marketing An independent variable is an input to a process or analysis that influences the dependent variable. While there can only be one dependent variable in a study, there may be multiple independent variables.ts name comes from the fact that it depends on or responds to other variables. Typically, the dependent variable is the result you want to achieve. In marketing, the results desired are tied to sales revenue.

Dependent Variable Definition and Examples Common Misspellings: dependant variable. Examples: 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 and the moth's reaction is the dependent variable. A change in the independent variable (amount of light) directly causes a change in the dependent variable (moth behavior).

Dependent variable Manipulated variable. Definition. noun, plural: manipulated variables. The variable that is manipulated in an experiment to determine its effect(s) on variable(s) reliant to it. Supplement. For example: An experiment is designed to see if a newly developed drug is effective in treating patients with cough. Some of the patients were given the drug while others the placebo.

Whats the difference between independent and dependent variables? also, theory and hypothesis? The independent variable is the one the experiment is manipulating in order to measure it's effect on the dependent variable. So if you wanted your dog to stop barking, you would try spraying it with water when it barked.

Research Variables: Dependent, Independent, Control, Extraneous & Moderator A variable is defined as anything that has a quantity or quality that varies. The dependent variable is the variable a researcher is interested in. An independent variable is a variable believed to affect the dependent variable. Confounding variables are defined as interference caused by another variable.

Independent and Dependent Variable Examples Independent Variable. The independent variable is the condition that you change in an experiment. It is the variable you control. It is called independent because its value does not depend on and is not affected by the state of any other variable in the experiment.

What is an independent variable? An independent variable is the variable that the scientist changes,  and the dependent variables are the variables that the scientist  doesn't control.
