What's the difference between effectiveness and efficiency?

Effectiveness


Definition:

  • (17) Simplicity, high capacity, low cost and label stability, combined with relatively high clinical sensitivity make the method suitable for cost effective screening of large numbers of samples.
  • (18) In dogs, cibenzoline given i.v., had no effects on the slow response systems, probably because of sympathetic nervous system intervention since the class 4 effects of cibenzoline appeared after beta-adrenoceptor blockade.
  • (19) The effects of sessions, individual characteristics, group behavior, sedative medications, and pharmacological anticipation, on simple visual and auditory reaction time were evaluated with a randomized block design.
  • (20) Urinary ANF immunoreactivity was significantly enhanced by candoxatril in both groups (P less than 0.05 and P less than 0.01 in groups 1 and 2, respectively), with a more pronounced effect evident at the higher dose (P less than 0.01).

Efficiency


Definition:

  • (n.) The quality of being efficient or producing an effect or effects; efficient power; effectual agency.
  • (n.) The ratio of useful work to energy expended.

Example Sentences:

  • (1) Theoretical findings on sterilization and disinfection measures are useless for the dental practice if their efficiency is put into question due to insufficient consideration of the special conditions of dental treatment.
  • (2) The hemodynamic efficiency of the drive was tested in a number of in vivo experiments.
  • (3) This may be due to efficient replacement of Leu by Phe at CUC (and, probably, CUU) codons throughout the genome.
  • (4) Meanwhile the efficiency of muscarinic antagonists in inhibition of tremor reaction induced by arecoline administration is associated with interaction between the drugs and the M2-subtype.
  • (5) These lysates are comparable to those of Escherichia coli in transcriptional and translational fidelity and efficiency in response to a given template DNA.

  • (9) Epidermal growth factor reduced plating efficiency by about 50% for A431 cells in different cell cycle phases whereas a slight increase in plating efficiency was seen for SiHa cells.
  • (10) It is argued that this process drove the evolution of present 5' and 3' splice sites from a subset of proto-splice sites and also drove the evolution of a more efficient splicing machinery.
  • (11) Nevertheless, this LTR does not govern efficient transcription of adjacent genes in a transient expression assay.
  • (12) This new protocol has increased the effectiveness of the toxicology laboratory and enhanced the efficiency of the house staff.
  • (13) It is proposed that microoscillations of the eye increase the threshold for detection of retinal target displacements, leading to less efficient lateral sway stabilization than expected, and that the threshold for detection of self motion in the A-P direction is lower than the threshold for object motion detection used in the calculations, leading to more efficient stabilization of A-P sway.
  • (14) Although they were praised in the last five years as the most efficient drugs against cancer and infectious diseases, no great success was clinically and experimentally reported in the past.
