Is the scientific method a linear process?

Not a linear, but somewhat circular, this entail you to go back and revise and retest your hypothesis and experiment. becouse the scientific method is not a linear process, so it will describe each step as a series of phase.

The scientific process is a procedure for research that is used to explore observations, it may be accepted as a theory and used to explain the phenomena in question. Thus, the scientific method is not a linear process of steps, but a method of inductive reasoning.
