Validity and Reliability. . . . . The principles of validity and reliability are fundamental cornerstones of the scientific method. This article is a part of the guide:
The scientific method is the process by which science is carried out. As in other areas of inquiry, science (through the scientific method) can build on previous knowledge and develop a more sophisticated understanding of its topics of study over time.This model can be seen to underlay the scientific revolution.hough the scientific method is often presented as a fixed sequence of steps, it represents rather a set of general principles. Not all steps take place in every scientific inquiry (or to the same degree), and are not always in the same order.
