Explanation: Which of the following is a best practice when implementing an experiment?


Explanation: When implementing an experiment, adhering to the best practice of **testing one variable for each experiment** is crucial for obtaining clear and actionable results. By isolating and manipulating only one variable at a time, researchers can accurately determine its impact on the outcome without interference from other factors. This method allows for a systematic and controlled approach to experimentation, enabling researchers to draw valid conclusions about cause and effect relationships. Testing multiple variables simultaneously can lead to confounding results, as it becomes challenging to discern which variable caused a particular outcome. Additionally, focusing on a single variable streamlines the experimental process, making it easier to design, execute, and interpret the study. Overall, by adhering to the best practice of testing one variable for each experiment, researchers can conduct rigorous and reliable experiments that yield meaningful insights and drive informed decision-making.
