degree of freedom
A positive integer that gives the number of pieces of data that are independent. The degree of freedom, in other words, expresses the number of options available within a variable or space. In a system with n states the degree of freedom is n. In the statistics of the n cells of a table of probabilities only n-1 can be arbitrarily filled, the last being determined by the requirement that probabilities must add to 1; hence the degree or freedom is n-1.
