Because if you change 2 parameters, you don't know which caused the potential change in outcome.

Well, the reason is simple. If you control everything but 1 parameter, then you can be absolutely certain that any change in outcome was due to THAT parameter.

You need to be able to point to the one difference that caused a different outcome.

If you change two factors, you won't know which one caused the different outcome.
