The term "inductive reasoning" refers to reasoning that takes specific information and makes a broader generalization that's considered probable, while still remaining open to the fact that the conclusion may not be 100% guaranteed.
In other words, you're making an educated or informed guess based on the information or data that you have. It might sound right, but that doesn't mean it is right. Together, let's explore some examples of inductive reasoning. You'll quickly see what it's all about.
There are varying degrees of strength and weakness in inductive reasoning. There are also various types including statistical syllogism, arguments from example, causal inference, simple inductions, and inductive generalizations. They can have part to whole relations, extrapolations, or predictions.
Some examples of inductive reasoning include:
