# What is the difference between a manipulated and a dependent variable?

###### Wiki User

The manipulated variable is the variable that is changed in an experiment and the dependent variable is what is measured. For example, let's say you are interested in how stress affects heart rate in humans. Your independent variable would be the stress levels and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.

The difference is that the independent variable is the one being changed (manipulated), dependent is not.

The independent variable is the variable that is manipulated. This affects the dependent variable and the results of the experiment.

The independent variable is the value being manipulated or changed, while the dependent variable is the observed result of the independent variable being manipulated. "IF" you change the independent variable, "THEN" what happens to the dependent variable?

The Independent Variable is the variable being manipulated. The dependent variable is what your trying to get a conclusion of.

The independent variable is the variable being manipulated in the experiment in order to show the effect on the dependent variable. It is also called the experimental variable.The dependent variable is the variable being observed in the experiment. Changes in the dependent variable as a result of changes in the independent variable are observed, which is the purpose of the experiment. Dependent variable is also called the response variable.

A manipulative variable is the variable you can alter, while the responding variable is the variable you have no control over. A manipulated variable is what is changed purposely throughout the experiment. The responding variable is which you have to measure to get your results I think. But the responding variable depends on the dependent variable. I believe I'm right!

In an experiment, the independent and dependent variables are very closely related. The independent variable is the element that is manipulated, and the dependent variable changes depending on what is done to the independent variable.

It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.

A manipulated variable is the variable that has been changed in the experiment. A responding variable is the variable that has been kept through the whole experiment.

Manipulated variables are also known as independent variables. These are the variable which you change in an investigation. Plotted on the x axis.

The dependent variable changes as a result of changes in the independent variable.Put another way,The Independent Variable is manipulated, and is known as the changed variable.The Dependent Variable is responding, and is known as the result.Example : In an experiment to test the effect of heating on evaporation, the various temperatures would be the independent variable, which will be changed by the experimenter. The amount of water that evaporates in a given time is the dependent variable, which is the data sought in the experiment.

An independent variable is the variable you can change in an experiment. On a graph, it's on the X-axis. A dependent variable is the result of changing the independent variable. It is literally dependent on it. The dependent variable goes on the Y-axis.

independent variable is the one you control. the dependent variable depends on the indepdendent variable (the results). on the graph independent in on the bottom and dependent is on the side

The independent variable is what you did differently in the experiment compared to the controlled experiment; it's also called manipulated variable. The dependent variable is what changed in the experiment as a result of the independent variable; it's also called the responding variable x hope this helps :)

A dependent variable can vary as the experiment goes on. The independent will not change during the experiment.

Dependent variable is your data, independent variable is what you are testing. Ex. Sunlight would be the independent variable and a plants growth would be the dependent variable.

An independent variable can be any of a given set of values while a dependent variable is represented as a function of another variable.

In an experiment the independent is the stimulus, the thing controlled or applied by the experimenter. The dependent variable is the response, the reaction to the independent variable.

In an experiment, the independent variable is the variable that can be altered or controlled to produce a change. The result being studied is the dependent variable, which is observed to change as the independent variable is changed.Example : In an experiment testing the effect of caffeine on reaction times, the amount of caffeine consumed is the independent variable and can be varied. The reaction times are the dependent variable, and a correlation (change in times) with the independent (amount given) is the information being sought.There are three kinds of variables. These are:Independent variable: is not affected by any effects in the experimentDependent variable: its reaction does depend on other variablesControlled variable: variable that you can control throughout the entire experimentTo put it simply, the independent variable tries to manipulate the dependent variable in an experiment.The independent variable (manipulated variable) is a variable that is changed by the experimenter. The dependent variable (responding variable) is what you are trying to determine in an experiment. My 6th grade science teacher taught us a poemThe manipulated is what you control the responding variable is your ultimate goal.

in a scientific expiriment, the control (controlled variable) is the variable that stays the same between trials. the manipulated variable is the variable that you change between trials. for instance if you are measuring the effect of light on a growing plant, your contol would be the amount of water you use. the manipulated would be the amount of sunlight. there is also another variable. the independent variable. this is the one that changes between trials. it would be the amount of growth in the plant scenario.

A dependent variable that can take on an infinite or at least very large number of values, such as rate of return. In statistical analysis, a dependent variable that is grouped into two or more categories such as solvency/insolvency.

The manipulated variable is the variable which researches change, while the measured variable is the variable that changes as a result of the manipulated variable. Consider this simplified question: Do flowers grow better with more water? Researchers plant flowers and put 10mL in one pot, 20mL in another, and 30mL in another. This is the manipulated variable. Researchers measure how tall the flowers are. The height of the flowers is the measured variable, because it changes as a result of the amount of water added.

a dependent variable is something that you cannot change but comes out as a result/an independent variable is something that you change in your experiment like the temperature of something or the amount of something

For example in the sraight line equation of y = 2x+6 it is y that is the dependent variable because its value is determined by the independent variable of x
