In statistics, deviance is a goodness-of-fit statistic for a statistical model; it is often used for statistical hypothesis testing. It is a generalization of the idea of using the sum of squares of residuals (SSR) in ordinary least squares to cases where model-fitting is achieved by maximum likelihood .
Absolute deviation in statistics is a metric that measures the overall difference between individual data points and a central value, typically the mean or median of a dataset. It is determined by taking the absolute value of the difference between each data point and the central value and then averaging these absolute differences. [4]
Note that, because of the definition of the sample mean, the sum of the residuals within a random sample is necessarily zero, and thus the residuals are necessarily not independent. The statistical errors, on the other hand, are independent, and their sum within the random sample is almost surely not zero.
In probability theory and statistics, variance is the expected value of the squared deviation from the mean of a random variable. The standard deviation (SD) is obtained as the square root of the variance. Variance is a measure of dispersion, meaning it is a measure of how far a set of numbers is spread out from their average value.

HuffPost and The Chronicle examined 201 public D-I schools from 2010-2014. Schools are ranked based on the percentage of their athletic budget that comes from subsidies.
Deviance (statistics), a quality of fit statistic for a model; Positive deviance, an approach to behavioral and social change; Sexual deviance (historical term) or paraphilia, recurring or intense sexual arousal to atypical things; Deviance or bid'ah, innovations and deviant acts or groups from orthodox Islamic law (Sharia)
Notes: Precinct data not yet available for Connecticut districts. Some Virginia voting districts are split, meaning that some precincts fall in two districts. The full precinct is counted here in the general election results when part of the precinct falls within the district because they are not further broken down.
An earlier study, conducted in 2017 and matched to nationally representative data, found that the public health impacts of politics are comparable to or worse than those associated with alcohol.
