Why does the investigator in an experiment change only one variable?

the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.

Why does an investigator change only one variable in an experiment?
So the variable can be at constant.
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.
How many variables do you change at one time during an experiment?
You only change one variable; if you changed multiple variables you wouldn't know which one caused a change.
What type of experiment is one in which only one variable at a time is changed?
a controlled experiment
Why does an investigator change only one variable in an experiment?
So the variable can be at constant.
What is a variable that is change in an experiment?
The dependent variable is the variable that can change in an experiment.
In an experiment where you change only the temperature temperature is the?
manipulated variable
How many things can you change in an experiment?
You only change 1 iv ( independent variable in a experiment ) HOPE IT HELPS :)
Are variable in an experiment can change True or False?
A variable does and must change, but you can only have one variable, otherwise the experiment becomes biased and unfair
What is the temperature called when in an experiment you only change the temperature?
dependent variable
What is a scientifict controlled experiment?
It is an experiment in which only one variable is changed for example if I was seeing where a banana rotted fastest the only variable that would change is where the banana is placed.
Why is it imporatant to change systematically only one variable at a time when doing the experiment?
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
What is The thing you change in an experiment?
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
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
Why should an experiment be tested only one variable at a time?
if you change more than one variable, you will not know which one has had an effect on the experiment. If the outcome changes when one variable is altered, then the change can only be due to the one variable, by logical deduction.
When a experiment only has one variable that can change and all other variables are kept unchanged this type of experiment is an?
it is a fair test
