What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements and can be counted or measured.

What is the significance of replicating experiments?

Back

Replicating experiments is important to verify results and ensure that findings are reliable and not due to chance.

Front

What is a scientific theory?

Back

A scientific theory is a well-substantiated explanation of an aspect of the natural world that is based on a body of evidence and has stood up to repeated testing.

What role does peer review play in scientific research?

Back

Peer review is a process where other experts evaluate research before it is published, ensuring the quality and credibility of the work.
