skew adj : having an oblique or slanting direction or position; "the picture was skew" [syn: skewed] v : turn or place at an angle; "the lines on the sheet of paper are skewed" [ant: align]
EtymologyFrom etyl fro escuer/eskiuer, northern variants of eschuer/eschiver/eschever.
- (US) SAMPA:/skju/
- Rhymes with: -uː
- To change or alter in a particular direction.
- A disproportionate number of female subjects in the study group skewed the results.
to change or alter in a particular direction
- Czech: zkreslit
Skew or skew lines lie on different planes. They are neither parallel nor intersecting.
- In parallel transmission, the difference in arrival time of bits transmitted at the same time.
Nte: Skew is usually interpreted to mean the difference in reading times between bits recorded on the tracks at the extremities, or edges, of the tape.
Note: Skew is expressed numerically as the tangent of the deviation angle.
- In facsimile, the angle between the scanning line, or recording line, and the perpendicular to the paper path.
- Example of +1 degree (counter-clockwise) skew in a facsimile image. The red line is perfectly horizontal.
- In reference to computer disk drives, track-to-track skew is the angle between the start of the data on a given track and the start of the data on the next. This is important, as when reading the data in sequence from one track to the next, time must be allowed for the read/write head to move to the next track, during which the disk continues to rotate. Insufficient skew can force the drive to wait almost an entire revolution for the data to pass under the head again, resulting in extra revolutions per track to read the data. Excessive skew can also lower the sustained data transfer rate.
Computer graphicsSkew is a common term for the shear mapping.
In optics, a skew ray is an optical path through a rotationally symmetric optical system that is not in a plane of symmetry.
