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!

## Related Questions 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 difference is that the independent variable is the one being changed (manipulated), dependent is not. A controlled experiment is useful to examine the relationship between a manipulated variable and a responding variable. the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment. That is the point of doing the experiment. You are trying to find out if there is any relationship at all. 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 :) The independent variable is the variable that is manipulated. This affects the dependent variable and the results of the experiment. 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. 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. What will be the manipulated variable and responding variable of this research topic? Think it's a good idea to plug into iTunes, surf the Web, or watch TV while doing homework or trying to read? Lots of people do it and claim that jumping from one activity to another keeps their attention level up and even gives their brain some time to "relax" between the more challenging tasks. Just how efficient is multitasking? 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.  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. 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. An individual difference variable are variables that occur naturally and that a researcher cannot assign a participant to. These include gender, age, height, etc. A manipulated variable a researcher can assign a person to such as a placebo group vs the actual medicine. 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. 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.   A variable is something which can change, that is have different values.The proper scientific terms for these are: Dependent and Independent variable. The independent variable is the thing that you vary during an experiment. The dependent variable is what changes as a result of that manipulation.A manipulated variable is the variable which you deliberately alter the value of. So, you will know the values of this variable before you do the experiment. This variable is also called the independent variable.A responding variable is the variable which you have to measure to get your results. So, you do not know the values of this variable until you measure it. This is also called the dependent variable.For example, to find out if your heart rate depends on exercise, you could do different amounts of exercise (the manipulated variable) and measure the heart rate (the responding variable).The above answer is well written, so I will just add a couple of examples.The standard linear equation is defined as 'y = mx + b'. y = 4x + 10, for example, could be charted on a Cartesian coordinates graph as a straight line that has a slope of 4 and a y-intercept of 10. In such linear equations, x would be described as the manipulated, or independent variable, while y would be the responding, or dependent variable.In another example suppose you are traveling in a car at 50 miles per hour. How far would you go if you traveled three hours? In this example, x would be the number of hours traveled, and y would be the total distance traveled in miles. The equation would be y = 50x. In this equation, x is the independent variable, and y is the dependent variable. By substituting 3 for x (because the question asked how far would you go in three hours), we can calculate that you would travel 150 miles. So the distance you travel (y) depends upon how long you traveled (x). 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. The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen. scientists use this to examine the relationship between a manipulated variable.
