Skew may refer to:

In mathematics:

In statistics:

• Skewness, a measure of the asymmetry of a probability distribution
• Skew normal distribution, a continuous probability distribution that generalises the normal distribution to allow for non-zero skewness

In chemistry

• Skew (also synclinal or gauche), a torsion angle between 30° to 90° and –30° to –90°; see Alkane stereochemistry

In optics:

• A skew ray, an optical path through a rotationally symmetric optical system that is not in a plane of symmetry

In engineering:

• A skew arch, a method of construction that enables an arch bridge to span an obstacle at some angle other than a right angle

In finance:

In telecommunications:

• Skew (fax), the angular deviation of the received frame from rectangularity
• In parallel communication, the difference in arrival time of simultaneously transmitted bits
• For data recorded on multichannel magnetic tape, the difference between reading times of bits recorded in a single transverse line. 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.
• Skew (antenna) a method to improve the horizontal radiation pattern

In computers:

• Clock skew, a phenomenon in which the clock signal arrives at different components at different times.
• 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.
• Transitive data skew

In aviation:

In fantasy baseball:

• SKEW, a strategy that focuses on high impact middle relievers that register a lot of strikeouts

In carpentry or construction:

• Skew nail or skew screw, a technique whereby a nail or screw is driven at the angle required to create a sound join between two or more pieces of material (generally timber).
