Can an experiment that has several variables be used to explain a theory?

Question

explain your answer

Answer 1

That's a theory in and off itself - and the reason long term weather forecasts are so damned hard to calculate - there's just too many variables.

Obviously, too many variables will make any theory impossible to validate by other scientists - each putting in different variables and coming up with different results.

Answer 2

Yes. It just means the data is maybe a 3-dimensional graph instead of 2 dimensional, or even multi dimensional. PVT graphs for a gas come to mind.
