There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
There is no limit to the number of variables a formula can have.

An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
As many as are necessary, as few as possible.
This questions is two broad and has too many variables to answer effectively.
If you change the variables in a science experiment, you will probably get different results.

There is no limit to the number of variables a formula can have.
You get a set of points that appear to be scattered randomly.
This question cannot be answered, as there are simply too many variables. Any attempt to provide an answer would consist of nothing but useless generalizations.
Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.
Weather-modeling software must account for many variables.
Yes. If you have too many variables, you cannot be sure what caused the results.
1) I learned that you can have as many variables as you want. 2) You can change the variables. 3) Variables is used in an experiment. 4) A variable is something that can be changed, such as a characteristic or value. Variables are generally used in Psychology experiments to determine if changes to one thing result in changes to another.
