Does a change in one variable cause a change in anther variable?

Supplemental: If there are different variables on two sides of an equation, a change in either variable will inevitably change the variable on the other side to make the equation true. Example: A + B = C, where A = 5 and B = 6, C = 12. If A = 7 and B = 6, C changes to 13. As you can see, changing A to 7 from 5 changed C, but not B. The good rule of thumb being, if one side changes, the other side does as well. -Jonathan C. Holcomb _____________________________________________________________________________
I don't know in what context are you talking about.
But if you apply this question to everything you know the anser is NO.
A change in a certain variable does not implies a change in another one.
This does not mean that some variables are not affected by others, but the statement cannot be applied to every variable.

What makes one variable cause the second?
A variable does not usually "cause" another. A change in one variable may result in a change in another. Such a change may be systematic (the relationship between the two variables is precise) or it may be statistical or correlational. The reasons for either type will often depend on disciplines of knowledge other than mathematics, such as physics or economics etc.
Does the independent variable really change independently of the other variable?
The relationship is a matter of cause and effect. An independent variable is given as one upon which another variable depends. So, for example, if you heat a metal pipe, the pipe expands. The amount of expansion is dependent upon the amount of heating that occurs, so expansion is the dependent variable, and the heating, which you may or may not control, is the independent variable. All it means is that if the independent variable ungoes a change, there is an associated and predictable change in the dependent variable. The two are linked inextricably, but one is cause, the other is effect, or to put it another way, you control the change in the dependent variable with input into the independent variable, but it doesn't normally work the other way around.
Why is it important to not change your variable in an experiment?
If you change more that one variable in an experiment, then when the result occurs, you won't know which variable caused the change.
What is the variable you control?
The Independent Variable is the one you change (Independent = I change)The Dependent Variable is the one you measure (It depends on something else)The Control is the one you keep the same! :)
What are science variables?
There are three different types of variables in science.Independent Variable: The one you choose to change. Or it is the cause of the change in the dependent variable. (Ex: amount/type of Fertilizer)Dependent Variable: The one you choose to observe. The one that receives the effect of the independent variable. (Ex: Plant ; the one you'll use with the fertilizer)Controlled Variables (Usually more than one): The ones that remain the same throughout the experiment.
In a controlled experiment what group is the group that has one variable changed?
I believe the what your referring to is the independent variable (changed). This is chosen and it is the relationship between the change in the independent variable which will cause a change in the dependent variable.
How many variable should be tested and isolated in a good experiment?
One. If there is only one variable being tested, when you compare it to the control, you know that was the cause of a change.
What makes one variable cause the second?
A variable does not usually "cause" another. A change in one variable may result in a change in another. Such a change may be systematic (the relationship between the two variables is precise) or it may be statistical or correlational.

What is the experimental variable?
The independent variable is the one variable that you change in your experiment
What is experimental Variable?
The independent variable is the one variable that you change in your experiment

Is the independent variable the one that does not change?
No, as the name Variable implies, it can and does change. Since it is 'Independent' its change is not a direct effect of the change of any other Variable. Additionally, the independent variable depends on the dependent variable.
What is the variable called that will change in an experiment?
An experiment is almost always designed so that two (and no more) things will change.-- You, the experimenter, will change one of them as you desire.-- That will cause a change in the other one, which you will carefully measure.
Why is it important to not change your variable in an experiment?
If you change more that one variable in an experiment, then when the result occurs, you won't know which variable caused the change.
What does a rate of change indicate?
The rate of change indicates the change in one variable per unit change in a second variable at (or around) that level for the second variable.
What is the variable you control?
The Independent Variable is the one you change (Independent = I change)The Dependent Variable is the one you measure (It depends on something else)The Control is the one you keep the same! :)
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.
