What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

Front

What is an experiment?

Back

An experiment is a structured procedure carried out to investigate a hypothesis by manipulating variables and observing outcomes.
