It seeks the most likely explanation for a set of observations, rather than proving a conclusion.

Front

How does Inductive Reasoning work?

Back

It works by gathering specific instances or examples and forming a broader generalization or theory based on those instances.

What is a common use of Deductive Reasoning in everyday life?
