Which of the following is a reason for conducting scientific investigations?

Conducting scientific investigations is essential for establishing procedures that can yield reliable and repeatable results. Establishing procedures involves developing a systematic approach to experimentation, which includes defining methods, identifying controls, and determining how data will be collected and analyzed. This structured methodology is fundamental to ensuring that experiments are conducted in a way that minimizes bias and maximizes accuracy, allowing scientists to draw valid conclusions based on their findings.

While testing assumptions and eliminating variables are indeed important aspects of scientific inquiry, the primary focus of conducting an investigation revolves around the establishment and adherence to established procedures that guide the research process. This enables the scientific community to communicate findings effectively and replicate studies, ultimately advancing knowledge and understanding in various fields of science.
