Exploring Experimental Design in Health Research

The purpose of conducting experiments in science is to support or reject hypotheses.

A hypothesis becomes a theory when it is supported by a significant amount of peer-reviewed experiments.

Peer review is the evaluation of a proposed publication by scientists in the same field, who determine its credibility and propose changes if necessary.
