What's the difference between experiment and hypothesis?

Experiment


Definition:

  • (n.) Atrial or special observation, made to confirm or disprove something doubtful; esp., one under conditions determined by the experimenter; an act or operation undertaken in order to discover some unknown principle or effect, or to test, establish, or illustrate some suggest or known truth; practical test; poof.
  • (n.) Experience.
  • (v. t.) To make experiment; to operate by test or trial; -- often with on, upon, or in, referring to the subject of an experiment; with, referring to the instrument; and by, referring to the means; as, to experiment upon electricity; he experimented in plowing with ponies, or by steam power.
  • (v. t.) To try; to know, perceive, or prove, by trial experience.

Hypothesis


Definition:

  • (n.) A supposition; a proposition or principle which is supposed or taken for granted, in order to draw a conclusion or inference for proof of the point in question; something not proved, but assumed for the purpose of argument, or to account for a fact or an occurrence; as, the hypothesis that head winds detain an overdue steamer.
  • (n.) A tentative theory or supposition provisionally adopted to explain certain facts, and to guide in the investigation of others; hence, frequently called a working hypothesis.
