Variation vs. Skewness — What's the Difference?

A change or slight difference in condition, amount, or level, typically within certain limits

In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined.

A different or distinct form or version of something

To turn or place at an angle

The act, fact, or process of varying.

To give a bias to; distort

The extent or degree to which something varies

To take an oblique course or direction.

Something different from another of the same type

To look obliquely or sideways.

Magnetic declination.

To display a statistical tendency toward

(Biology) The existence within a species or other group of organisms of differences in form, function, or behavior, especially when hereditary.

Placed or turned to one side; asymmetric.

(Mathematics) A function that relates the values of one variable to those of other variables.

Distorted or biased in meaning or effect.

A form that is an altered version of a given theme, diverging from it by melodic ornamentation and by changes in harmony, rhythm, or key.

Having a part that diverges, as in gearing.

One of a series of forms based on a single theme.

(Mathematics) Neither parallel nor intersecting. Used of straight lines in space.

A solo dance, especially one forming part of a larger work.

(Statistics) Not symmetrical about the mean. Used of distributions.

The act of varying; a partial change in the form, position, state, or qualities of a thing.

An oblique or slanting movement, position, or direction.

A related but distinct thing.

The property of being skew.

(nautical) The angular difference at the vessel between the direction of true north and magnetic north.

(statistics) A measure of the asymmetry of the probability distribution of a real-valued random variable; is the third standardized moment, defined as $\backslash scriptstyle\backslash gamma\_1\; =\; \backslash frac\{\backslash mu\_3\}\{\backslash sigma^3\},\; \backslash !$ where $\backslash mu\_3$ is the third moment about the mean and $\backslash sigma$ is the standard deviation.

(board games) A line of play that differs from the original.

An oblique or slanting asymmetry

(music) A technique where material is repeated with alterations to the melody, harmony, rhythm, timbre, texture, counterpoint or orchestration; but with some invariant characteristic, e.g. a ground bass.

(genetics) The modification of a hereditary trait.

(astronomy) Deviation from the mean orbit of a heavenly body.

The act of varying; a partial change in the form, position, state, or qualities of a thing; modification; alteration; mutation; diversity; deviation; as, a variation of color in different lights; a variation in size; variation of language.

Extent to which a thing varies; amount of departure from a position or state; amount or rate of change.

Change of termination of words, as in declension, conjugation, derivation, etc.

Repetition of a theme or melody with fanciful embellishments or modifications, in time, tune, or harmony, or sometimes change of key; the presentation of a musical thought in new and varied aspects, yet so that the essential features of the original shall still preserve their identity.

One of the different arrangements which can be made of any number of quantities taking a certain number of them together.

An instance of change; the rate or magnitude of change

An activity that varies from a norm or standard;

A repetition of a musical theme in which it is modified or embellished

Something a little different from others of the same type;

An artifact that deviates from a norm or standard;

The angle (at a particular location) between magnetic north and true north

(astronomy) any perturbation of the mean motion or orbit of a planet or satellite (especially a perturbation of the earth's moon)

(biology) an organism that has characteristics resulting from chromosomal alteration

(ballet) a solo dance or dance figure

The act of changing or altering something slightly but noticeably from the norm or standard;
