What is evidence in scientific claims?

Back

Evidence is the data or information that supports a claim or hypothesis. It can come from experiments, observations, or research studies.

What does CER stand for in scientific writing?

What is a claim in the CER framework?

Back

A claim is a statement or assertion that answers a research question or addresses a problem.
