Which of the following is a method used in the scientific approach?

The scientific approach is grounded in systematic methods that prioritize empirical evidence for understanding phenomena. Observation and experimentation are fundamental components of this methodology. Through observation, scientists collect data about the world around them, while experimentation allows them to test hypotheses under controlled conditions. This process is designed to minimize biases and errors, providing reliable, reproducible, and objective results.

In contrast, other methods listed, such as creating laws (which often follow from and require empirical support), making assumptions without data, and relying on anecdotal evidence, do not adhere to systematic and objective inquiry. Instead, they lack the rigor and reliability expected in scientific investigations. Thus, observation and experimentation form the backbone of a credible scientific approach, enabling researchers to build knowledge based on factual evidence rather than speculation or unverified claims.
