For instance, if this researcher wants to calculate sample variance to understand the extent to which incomes vary in this community, the degrees of freedom equal N - fc.The relation- ship between
The term is most often used in the context of linear models (linear regression, analysis of variance), where certain random vectors are constrained to lie in linear subspaces, and the number of degrees of freedom is the dimension of the subspace. The degrees of freedom are also commonly associated with the squared
