What's the difference between inference and observation?

Inference


Definition:

  • (n.) The act or process of inferring by deduction or induction.
  • (n.) That which inferred; a truth or proposition drawn from another which is admitted or supposed to be true; a conclusion; a deduction.

Example Sentences:

  • (14) The therapeutical inferences of these observations are discussed.
  • (15) We infer that a 5' cap is present on both of these RNAs and conclude that the mini-exon-derived RNA donates its 5' cap along with the mini-exon sequence to the pre-mRNA.
  • (16) Tonic sympathetic neural control of heart rate was inferred from bradycardia after treatment with the adrenergic neuron-blocking agent, bretylium tosylate.
  • (17) Two consequences of these conditions are (1) patient classification into syndrome types (e.g., phonological dysgraphia, agrammatism, and so forth) can play no useful role in research concerned with issues about the structure of normal cognitive functioning or its dissolution under conditions of brain damage; and (2) only single-patient studies allow valid inferences about the structure of cognitive mechanisms from the analysis of impaired performance.
  • (18) Results are discussed and inferences for better care, particularly of the mentally ill residents, are indicated.
  • (19) By way of conclusion, from our observations we may infer that neither age, nor sex nor location, save in the case of patients under the age of 40, have prognostic value in the evolution of the primary tumor, which will be noticeably better (lower percentage of relapses and longer illness-free period) in patients with a single tumor of low grade and state, and in general in patients receiving intravesical prophylactic chemotherapy treatment, and no difference is found between thio-tepa and adriamycin.
  • (20) Awareness of making dispositional inferences was only weakly correlated with disposition-cued recall.

Observation


Definition:

  • (n.) The act or the faculty of observing or taking notice; the act of seeing, or of fixing the mind upon, anything.
  • (n.) The result of an act, or of acts, of observing; view; reflection; conclusion; judgment.
  • (n.) Hence: An expression of an opinion or judgment upon what one has observed; a remark.
  • (n.) Performance of what is prescribed; adherence in practice; observance.
  • (n.) The act of recognizing and noting some fact or occurrence in nature, as an aurora, a corona, or the structure of an animal.
  • (n.) Specifically, the act of measuring, with suitable instruments, some magnitude, as the time of an occultation, with a clock; the right ascension of a star, with a transit instrument and clock; the sun's altitude, or the distance of the moon from a star, with a sextant; the temperature, with a thermometer, etc.
  • (n.) The information so acquired.

Example Sentences:

  • (1) The patterns observed were: clusters of granules related to the cell membrane; positive staining localized to portions of the cell membrane, and, less commonly, the whole cell circumference.
  • (2) However, this deficit was observed only when the sample-place preceded but not when it followed the interpolated visits (second experiment).
  • (3) In conclusion, in S-rats a glucose-stimulated insulin release is accompanied by an increase in IBF, but this is not observed in P-rats.

K., Romain, R. E., and Herz, R. E. (1987) Am.
