# degrees of freedom

degrees of freedom
the number of ways the members of a sample can vary independently; a numerical index of a family of probability distributions that corresponds to the number of independent variables in the definition of each member, e.g., the chi-squared distribution with n degrees of freedom is the distribution of the sum of squares of n standard normal deviations. Symbol ν.
