You linked a list of definitions of the scientific method. Obviously, those are only basic guidelines so you know you are performing the experiment or examining the evidence scientifically, not just making stuff up or including bias inadvertently.
In different disciplines the way you apply the scientific method depends on whether you are studying a living chimpanzee, a pile of rocks, a vial of an unknown chemical substance, some disease germs on a slide, an ice core from Greenland, a DNA sample on a drinking glass from a crime scene, or a bone fragment from an archeological dig. Or a smoking gun in someone's hand, with a dead person on the ground in front of them.
Whatever you are studying, you will be applying the scientific method
to show something has already happened in the past-- a criminal suspect used the drinking glass yesterday, so we can find him using the DNA he left on it, for example. Or, the Greenland ice core reveals
past centuries of climate data based on the kind of gases trapped in different layers of the ice. Or you find out that the chimp has learned how to use tools
from past trial and error. Or you find out the person holding the smoking gun probably did not fire it, because there is no gun residue on their hands. All stuff about the past.
There won't be easy 1,2,3 cookbook instructions for how to analyze all those different things included in a basic definition of the scientific method. It depends on the discipline and what you are trying to find out.
Is that what you are asking? I am not sure what more you expected a definition of the scientific method to give you.
