What's the difference between epochal and significant?

Epochal


Definition:

  • (a.) Belonging to an epoch; of the nature of an epoch.

Example Sentences:

  • (14) It is argued that, during the first two and last periods, all quantities of genetic interest, such as the gametic frequencies, the mean fitness, the linkage disequilibrium, and the linkage disequilibrium ratio, Z, change with time in essentially the same manner, characteristic of the particular epoch concerned and determined in this paper, and therefore, when quasilinkage equilibrium occurs, it is a transitional phenomenon.
  • (15) Evidence for the hypothesis was found only during the EEG-epoch one second before the answer.
  • (16) The automatic analysis scored fewer epochs as stages wake, rapid eye movement (REM), and 2 and more as stages 1, 3, and 4.

  • (18) In the first set of experiments (n = 8), placebo or CS (30 mg) was given, followed by four 15-min epochs of alveolar hypoxia (8% O2, 5% CO2, 87% N2) each separated by 30 min of alveolar normoxia (21% O2).
  • (19) Two averaging strategies were assessed: (1) averaging the entire pre- and poststimulus epoch point for point across individuals and (2) averaging the voltage of Pa at the latency of Pa for each individual.
  • (20) Finally, it is demonstrated that the probability of a false-positive decision may increase by an order of magnitude if the Rayleigh test is not performed once, for a fixed number of epochs specified in advance, but is carried out repeatedly during an ongoing experiment until either one of the tests indicates the presence of an evoked response or the upper limit for the number of epochs is exceeded.

Significant


Definition:

  • (a.) Fitted or designed to signify or make known somethingl having a meaning; standing as a sign or token; expressive or suggestive; as, a significant word or sound; a significant look.
  • (a.) Deserving to be considered; important; momentous; as, a significant event.
  • (n.) That which has significance; a sign; a token; a symbol.
