σ

The average of the squares of the deviations from the arithmetic mean of a data set. It is a statistic which represents the extent to which a set of observations, for example, of annual rainfall over a series of years, spreads about the mean. Where the observations are closely grouped, the variance is low. See standard deviation.

A written authorization, from the responsible agency, permitting construction in a manner which is not allowed by code or other regulations.

---

A measure of the extent to which interval values are clustered around a mean. Variance is calculated by averaging the squared deviations from the mean, and in so doing it takes into account both negative values and the occurrence of unusually high and unusually low values. A low variance indicates high homogeneity and high variance low homogeneity of data.

The discrepancy between what a party to a lawsuit alleges will be proved in pleadings and what the party actually proves at trial.

In zoning law, an official permit to use property in a manner that departs from the way in which other property in the same locality can be used.

The term variance is used both in litigation and in zoning law. In both instances it has the general meaning of a difference or divergence.

A party to a civil lawsuit or a prosecutor in a criminal trial must prove the allegations set forth in a complaint, indictment, or information. If there is a substantial difference or discrepancy between the allegations and the proof offered in support, a variance exists. For example, if the crime of robbery is alleged and the crime of burglary is proved instead, the failure of proof on the robbery charge constitutes a variance that will lead to the dismissal of the case.

Most U.S. communities have zoning laws that control and direct the development of property within their borders according to its present and potential uses. Typically, a community is divided into zoning districts based on the type of use permitted: residential, commercial, and industrial. Additional restrictions may limit population density and building height within these districts. A variance is an exception to one or more of the zoning restrictions on a piece of property.

A variance is different from a nonconforming use, which permits existing structures and uses to continue when zoning is first instituted. Once a zoning plan has been established, a property owner who wishes to diverge from it must seek a variance from the municipal government. The variance will be granted when "unnecessary hardship" would result to the landowner if it were denied. Although other forms of administrative relief from zoning restrictions are available, such as rezoning the area, variances are most frequently used.

There are two types of variances: area variances and use variances. An area variance is usually not controversial because it is generally granted due to some odd configuration of the lot or some peculiar natural condition that prevents normal construction in compliance with zoning restrictions. For example, if the odd shape of a lot prevents a house from being set back the minimum number of feet from the street, the municipality will usually relax the requirement.

Use variances are more controversial because they attempt a change in the permitted use. For example, if a lot is zoned single-family residential, a person who wishes to build a multifamily dwelling must obtain a variance. Residents of an area will generally object to applications for variances that seek to change the character of their neighborhood. Although the municipality may heed these objections, it will likely grant the variance if it believes unnecessary hardship would result without the variance. If, however, the owner seeking a variance for a multifamily dwelling bought the property with notice of the current zoning restrictions, the variance will probably be denied. Applicants for a variance cannot argue hardship based on actions they commit that result in self-induced hardship.

If many use variances are sought in a particular area on the basis of unique or peculiar circumstances, it may be a sign that the entire neighborhood needs to be rezoned rather than forcing property owners to seek variances in a piecemeal fashion. Properly used, variances provide a remedy for hardships affecting a single lot or a relatively small area.

One of the measures of the dispersion of data; the mean squared deviation of a set of values from the mean.

• additive genetic v. — that portion of phenotypic variance which is due to the additive effect of genes (V_A).
• analysis of v. — a statistical method for comparing values, expressed in terms of means or variance, of one or more variables in several subgroups of a population. Called also anova.
• non-additive genetic v. — that portion of phenotypic variance which is due to epistatic interactions (V_I) and dominance deviations (V_D).
• non-genetic v. — that portion of phenotypic variance which is due to non-genetic effects such as environment (V_E).
• phenotypic v. — a measure of the extent to which individuals vary in their phenotype (V_P). V_P = V_A + V_D + V_I + V_E.
• v. ratio distribution — see f distribution.
