The primary purpose of this paper is to present the issue of extrapolation, which is interesting from the perspective of contemporary philosophy of science. For its proper explanation, it is crucial to distinguish it from terms of similar meaning, such as analogy, induction or statistical inference. The second goal is to indicate key differences that exist between extrapolative inference and analogical reasoning. Because of this the ascertaining of the identification of these concepts would be a mistake though, of course, there is no way not to notice certain similarities.
