It has been shown that in calculating Mw, Mn, and Mv values of a nonfractionated polymer from the weights and molecular weights of fractions, corresponding averages for the individual fractions should be used. In calculating higher averages (Mz and Mz+1), the values of lower averages are also required. An analysis of errors which appear on neglecting these requirements, has been given.
