Extensive Definition

Screening, in general, is the investigation of a great number of something (for instance, people) looking for those with a particular problem or feature. One example is at an airport, where many bags get x-rayed to try to detect any which may contain weapons or explosives. People are also screened going through a metal detector. Even though the procedure aims at a large number of screens, it is always equivalent to sampling in statistics, because the complete population is almost always inaccessible for screening.
Screening has other, more specific meanings:
  • Screening (printing), a process that represents lighter shades as tiny dots, rather than solid areas, of ink
  • Electric field screening, in physics, the dampening of an electric field by mobile charges
  • In atomic physics and chemistry, screening effect refers to the observation that electronic properties of atoms are better described if atoms had a lower effective nuclear charge than that would be otherwise expected from the number of protons present
  • Screening (economics)
  • Screening (medicine)
  • Film screening, the display of a film in a movie theatre or screening room, for some special purpose such as testing or critical review
screening in Norwegian: Screening
