Question

Any argument that is not deductively valid, or deductively invalid, is called an ampliativeargument. The term refers to the fact that the conclusion of such argument goes beyond, or amplifies upon, the premises.

Accepted Answer

Remark on terminology: Again the notion of ‘invalid’ is so common and central, that it goes by many names. Other terms commonly used are inductive and non-demonstrative. I prefer ‘ampliative’ because it reminds us that the conclusion ‘goes beyond’ the premises, and it does not have the bad reputation that sometimes goes along with the word ‘induction.’
