What is it when you use reliable sources for research before you conduct an experiment?

Using reliable sources for research before conducting an experiment is known as conducting a literature review. This process involves gathering information from credible studies, articles, and other academic resources to understand existing knowledge and context related to your experiment. It helps to inform your hypothesis, refine your methodology, and ensure that your research is grounded in established findings. Ultimately, this practice enhances the validity and credibility of your experimental work.
