Experimental Design and Cause-and-Effect

The purpose of experimental design is to create controlled conditions for an experiment to limit the exposure to outside interference and form a conclusion based on the hypothesis.

A scientific theory explains why things occur the way they do after significant repeated experiments, while a scientific law is a pattern established through an equation.

To design a good experiment, one needs to have background knowledge in the area of the experiment they wish to perform and ensure they are using the proper equipment.
