During which step in the scientific method does one conduct an experiment?

Conducting an experiment falls under the step of designing the experiment. This stage involves planning out how the experiment will be carried out, which includes selecting variables, determining controls, and deciding on the methodology to test the hypothesis. It is a crucial step that directly leads to the implementation of the experiment itself. During this process, researchers create a structured approach to gathering data and testing their predictions in a controlled environment, ensuring that the results are valid and reliable.

In contrast, analyzing data happens after the experiment is conducted. This step involves reviewing and interpreting the results of the experiment to determine if the hypothesis was supported or refuted. Formulating a hypothesis is a preliminary stage where researchers create a testable statement based on observations. Making observations is the initial step that leads to the question and hypothesis development. Hence, the act of actually conducting the experiment is situated within the context of designing the experiment, making that the correct answer.
