What happens when more than one variable in an experiment is changed at a time?

Because you want to see how the experimental results change due to only that one variable change. If you used two variables, and the results varied, how would you know which variable contributed more to the change if at all? It can be done this way, but one variable at a time will allow you to make sense of your data much more efficiently.

What variable in an experiment is manipulated?
A manipulated variable is the thing that can be changed in an experiment. example; your trying to see what paper towel would be more absorbant, your manipulated viariable would be either the type of paper towel you use or the liquid you use to test the absorbancy.
What are the factors that can change in an experiment called?
Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. 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. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.

What is the definition of idependent variable?
An independent variable is a part of an experiment that might change due to the outcome not being a desired result. The person conducting an experiment about how a medicine might affect a person, might change the number of people tested to gain more insight into the results. The independent variable in that situation would be the number of test subjects.
What is a controlled expirement?
an experiment that can be controlled i did not know this That is not a good answer! A controlled experiment is: If you set up an experiment: Example: You have two plants. You want to know if fertilizing every day causes it to grow more. In your experiment everything has to be the same! Except one thing. You have to have the same type of dirt and pot and flower/vegetable. You have to water each of them every day. But, you fertilize ONE of them once a day until your results are clear to you, or when you want to stop testing. This way, you can see how the fertilizer effects the plant growth compared to just water every day. If you change more than one thing, like how much you water the plant, it is not a controlled experiment anymore. because then you won't know which variable (thing that you have changed) is taking effect. You wouldn't know if it was more water or the fertilizer, or both that is making the plant grow faster!
Why can there only be one variable in an experiment?
If you vary only one quantity in an experiment, then the results will be related to that quantity. If you vary two or more quantities, then the results will be ambiguous; you will not know what variation is responsible for the observed result.
In a experiment the variable that is changed or determined by manipulation of one or more factors?
Dependent Variable
The variable which is deliberately changed in experiment?
Independent, it is in the name, more variables are: dependant variable- the one you keep the same control variable- mearsuring variable
Why is only one variable changed in an experiment?
You can have more than one variable, but it would take longer to solve.
What happens when more than one variable changes during a scientific experiment?
The outcome of the experiment may not be linked to any one specific variable.
What variable is the part of the experiment that is affected by the independent variable that is being tested or the part that is changed by the person doing the experiment?
The variable of the experiment that is being tested or the part that is changed by the person doing the experiment is called the independent variable... Thank you for letting me answer goodbye... ;)
Variable is an experiment that is adjusted by the experimenters?
The variable that is being changed in the experiment is called the independent variable. The variable being tested is called the dependent variable. The constant is the one thing in the experiment that stays the same
What best describes the dependent variable in an experiment?
The factor in an experiment that responds to the manipulated variable
What is a non manipulated variable?
A manipulative or manipulated variable in an experiment is the variable that can be varied to give different results during the course of an experiment. For example to determine how much sugar will saturate a liter of water, we keep increasing the amount of sugar until the water becomes saturated. Here sugar is the manipulated variable. Very easy! At first, I was confused with it too!
How can you improve your data accuracy in a lab experiment?
According to the scientific method, any scientific experiment must be done at least 3 times. Also, only one variable can be changed in an experiment (the independent variable). Any more changes will will ruin your dependent variable (your results) and make your data unreliable. If your experiment fails, learn from it, redo the experiment, and change another variable.
What does independent variables in science?
Hello, Well what you would be looking for is what an independent variable means. Assuming you understand what a variable is and a dependant variable is, here goes: An independant variable is the variable which you change in an experiment. Note you can only have 1 variable that can change in an experiment and more than one independent variable will result in an unfair experiment. An example is an experiment looking at the growth of trees in the Dark, in a dimly lit room and in the direct sun. The independant variable is the location of the experiment, because this is what is being changed. Simply: The Independent Variable is the variable that is independent and you change. The dependant variable is what changes when the independent variable changes. To conduct an experiment, you will have an independent variable and change that to see how the dependant variable changes with the independent one. Hope I Helped
What variable is the part of an experiment that is being tested or the part that is changed by the person doing the experiment?
There are three kinds of variables in an experiment. The independent variable is what you change in the experiment. It is important that you have only one independent variable in your experiment. You would not be able to draw reliable conclusions from the experiment if you altered more than one experimental condition. The dependent variable is what you measure in the experiment. Unlike the independent variable, an experiment can have more than one dependent variable because variations in the independent variable can have many different effects. For example, you might measure length of leaves and weight of roots to assess the growth of radish plants. Dependent variables can include amounts as well as amount data. Such data cannot be measured but is still useful when you describe and compare it.
What is scientific Dependent variable?
A dependent variable is a factor in an experiment that is influenced by another factor. An example might help to clarify. You are performing an experiment in which you are observing how sunlight affects plant height. Plant height is the dependent variable because it is dependent upon how much sunlight the plant receives. Sunlight is an example of an independent variable. It is not influenced by anything in this experiment, but may be changed to observe its effect on the dependent variable. It is possible to have more than one dependent variable in an experiment, but only one independent variable.
