Question

Why is it important that we change only one factor when conducting an experiment?

Answer 1

Answer: If you change multiple factors in an experiment, then you wouldn't know which factor is responsible for any changes.

Step-by-step explanation:

If something changes when you change only one factor in an experiment, then you can easily note down the cause of said change.

Answer 2

Changing only one factor in an experiment is important because it allows you to isolate the effects of that particular factor on the outcome of the experiment. This makes it easier to identify the relationship between the factor you are testing and the outcome, and to draw conclusions about cause and effect. If you change multiple factors at the same time, it can be difficult to determine which factor is responsible for any changes you observe in the outcome, and your results may be less reliable. By keeping all other factors constant and only changing the one factor you are interested in, you can more accurately determine the effect of that factor on the outcome of the experiment.
