okay, anyone know this one?
- Why do you think it is wise to limit an experiment to test only one factor at a time?
by the way, this is 10th grade IPC, so if it's not too much trouble, can you not use terribly big/ hard words? plz and thank you very very much

Because multiple factors in the same experiment may affect the result all together,in this case it is difficult to detect exactly which factor has which effect on the original sample.

The answer you're looking for is:
"Testing one factor at a time allows the determination to be made the independent variable (the factor) is causing a change in the dependent variable (the experiment result) with reasonable certainty."
Now really it is usually a better idea to set up a matrix of test so that you can find interactions between multiple inputs.
I hope that helps.

One only tests one factor (or variable/parameter) at a time because any changes in the results must be attributed to that one changed variable. If you change two parameters (or variables) at once (e.g. pressure and temperature), then you can't be sure what caused the change (either pressure or temperature).
Hope these words weren't too *big* for a 10th grader...

I can tell you the answer, but if you read the text, you can find it for yourself and then I won't be doing your homework for you.
