What is the scientific method?

1. A method of research that relies on empirical evidence

2. An approach for developing testable hypotheses

3. A set of principles used to make accurate data-driven decisions

4. A method of analysis that uses controlled experiments

The correct answer is: A method of analysis that uses controlled experiments

The scientific method is a systematic approach used by scientists to study the natural world. It is a continuous cycle of making observations, developing a hypothesis, conducting experiments to test the hypothesis, analyzing the results, and drawing conclusions. Option A is incorrect because while the scientific method does rely on empirical evidence, it is not the only characteristic of it. Option B is incorrect because while the scientific method does involve developing testable hypotheses, it is not the only aspect of it. Option C is incorrect because while the scientific method does involve making accurate data-driven decisions, it is not the only purpose of it. Therefore, option D is the most accurate answer as it specifically refers to the use of controlled experiments, which is a crucial aspect of the scientific method.
