Which is the result of conducting a controlled experiment?

Conducting a controlled experiment is designed to yield reliable and valid data by isolating the effects of the independent variable while controlling for other variables. This allows scientists to determine causal relationships and make more accurate conclusions based on the data collected. When all other factors are kept constant except for the one being tested, the results are reproducible and can be trusted. Thus, the outcome of such an experiment is consistent, lending itself to scientific understanding and further research.
