Magnitude


Definition:

  • (n.) Extent of dimensions; size; -- applied to things that have length, breath, and thickness.
  • (n.) That which has one or more of the three dimensions, length, breadth, and thickness.
  • (n.) Anything of which greater or less can be predicated, as time, weight, force, and the like.
  • (n.) Greatness; grandeur.
  • (n.) Greatness, in reference to influence or effect; importance; as, an affair of magnitude.

  • (2) Thus, our study confirmed that male subjects with a history of testicular maldescent have an increased risk for testis cancer, although the magnitude of this risk was lower than suggested previously.
  • (3) In addition, despite the fact that the differences constitutes an information bias, the bias occurs in the same direction and magnitude in all the various subgroups and thus is nondifferential.
