The number of independent observations used.Synonyms: DF

In an unconstrained dynamic or other system, the number of independent variables required to specify completely the state of the system at a given moment. If the system has constraints, that is, kinem [..]

The number of individual scores that can vary without changing the sample mean. Statistically written as ‘N-1’ where N represents the number of subjects.

In biometrics it is a measurement used to determine how unique biometric data is.

1. Number of elements free to vary in a statistical calculation. See chi-square distribution. 2. Motor control. The joints and muscles that move to produce a movement.

An engineering concept used in MEMS that describes the directions in which an object can move and generally the number of independent variables in a dynamic system.

In mechanics, the total number of directions of motion of an assembly being evaluated. E.g. a ship or aircraft experiencing linear motion up and down, fore-and-aft and left-and-right motions as well a [..]

statistics - the number of independent data elements needed to calculate a statistical estimate or parameter in a model, usually listed as a column in an ANOVA table; means and other parameter estimates are usually reported with the associated df, usually calculated as (n - 1) or (n - 2)

The degrees of freedom of a statistical group are the number of values in the group which are free to vary. This number is usually one less than the sample size, the number of items in the group.

The number of independent units of information in a sample used in the estimation of a parameter or calculation of a statistic. The degrees of freedom limits the number variables that can be included [..]

are the possible directions of motion of a system. A solid body has six degrees of freedom, because you can move the body in three independent directions ( X , Y , Z ) and rotate it around each of the [..]

The number of degrees of freedom of a mechanical system is equal to the minimum number of independent coordinates required to define completely the positions of all parts of the system t any instant o [..]

A statistical term expressing the confidence in an estimated measurement. In a random signal 1 Average = 2 DOF)

The amount of values in a system possible of variation. A robotic joint is equal to one degree of freedom.

the number of directions a part can move within an assembly.

Each of N sampled data points is free to take on any value. When a parameter is estimated for this data, this freedom to vary is restricted. The precision of an estimate is a function of degrees of fr [..]

(DOF):

An estimate of the number of independent categories in a particular statistical test or experiment.

In multiple regression analysis, the number of observations minus the number of estimated parameters.

degree of freedom|lang=en

The number of independent directions or joints of the robot (R15.07), which would allow the robot to move its end effector through the required sequence of motions. For arbitrary positioning, 6 degree [..]

Degrees of Freedom (often abbreviated df or DOF) refers to the number of independent variables or parameters of a system. In various scientific fields, the word "freedom" is used to describe the limit [..]

In physics, the degrees of freedom (DOF) of a mechanical system is the number of independent parameters that define its configuration or state. It is important in the analysis of systems of bodies in [..]

In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary.The number of independent ways by which a dynamic system can move, [..]

In physics and chemistry, a degree of freedom is an independent physical parameter in the formal description of the state of a physical system. The set of all states of a system is known as the system [..]
