How many types of scientific evidence are there?

There isn't a single fixed number of scientific evidence types, but they are categorized by strength in hierarchies, typically ranging from weak (anecdotal, expert opinion) to strong (systematic reviews, meta-analyses, randomized controlled trials - RCTs). Key types include anecdotal, descriptive/observational (cohort, case-control), quasi-experimental, experimental (RCTs), and systematic reviews/meta-analyses, with RCTs often considered the gold standard for effectiveness, and systematic reviews combining multiple strong studies.
