Generalization
Step-by-step explanation:
A generalization is taking one or a couple of realities and making a more extensive, increasingly general explanation. Generalizations are valuable on the grounds that with them you don't have to examine each and everything in a class before you make an end.
A generalization is the detailing of general ideas from explicit cases by abstracting normal properties. Generalizations set the presence of an area or set of components, just as at least one normal attributes shared by those components (accordingly making a theoretical model).
