What's the difference between experimentation and testing?

Experimentation


Definition:

  • (n.) The act of experimenting; practice by experiment.

  • (17) This experimental system allows separation of three B lymphocyte developmental stages: early differentiation in vitro, progression to IgM secretion in vivo, and late differentiation dependent upon mature T lymphocytes in vivo.
  • (18) An experimental autoimmune model of nerve growth factor (NGF) deprivation has been used to assess the role of NGF in the development of various cell types in the nervous system.
  • (19) In the liver of albino rats with experimental thyrotoxicosis a study was made of nucleic acids and some indices of phosphorus metabolism: total and inorganic phosphorus, total and acid-soluble phosphorus, phosphorus of RNA, DNA and phosphoproteins.
  • (20) Current status of prognosis in clinical, experimental and prophylactic medicine is delineated with formulation of the purposes and feasibility of therapeutic and preventive realization of the disease onset and run prediction.

Testing


Definition:

  • (p. pr. & vb. n.) of Test
  • (n.) The act of testing or proving; trial; proof.
  • (n.) The operation of refining gold or silver in a test, or cupel; cupellation.

Example Sentences:

  • (5) Clinical surveillance, repeated laboratory tests, conventional radiology, and especially ultrasonography and CT scan all contributed to the preoperative diagnosis.
  • (6) The hypothesis that proteins are critical targets in free radical mediated cytolysis was tested using U937 mononuclear phagocytes as targets and iron together with hydrogen peroxide to generate radicals.
