degree of freedom Line breaks: de¦gree of free|dom

Definition of degree of freedom in English:


1Each of a number of independently variable factors affecting the range of states in which a system may exist, in particular any of the directions in which independent motion can occur.
Example sentences
  • Since rigid vibration is assumed, only a single degree of freedom exists, and structural relations within the organ of Corti should remain static during motion.
  • Figure 8 shows the mathematical model of the temporary barrier system with the kinematic degrees of freedom.
  • The explanation of this feature is that the model has more parameters than the degree of freedom of the system.
1.1 Chemistry Each of a number of independent factors required to specify a system at equilibrium.
Example sentences
  • This may be explained by an increasing degree of freedom of the side chains of the aromatic amino acids.
  • This is very important for folding simulation because the degrees of freedom of a protein molecule are very large and there are many local minima in the folding path.
  • For an intermolecular disulfide bond within a beta-structure, segmental flexibility is less important because of the higher degree of freedom of the system of two separate molecules.
1.2 Statistics The number of independent values or quantities which can be assigned to a statistical distribution.
Example sentences
  • As a consequence, covariance matrices of the coordinate data are not of full rank, and the degrees of freedom for some statistical tests need to be adjusted.
  • Even though in geometry 2 points define a line, empirical studies require at least 3 points to add an additional degree of freedom for statistical computations.
  • The tabulated P value was calculated for every test statistic, using an F distribution with the appropriate degrees of freedom.
