- The possibility of using the G index and its generalizations in the six basic factor analytic designs is discussed. For O- and Q-analyses G should be used if there is no mutual direction of all the variables, as G is invariant over variable reflection. In all the six designs G should also be used if the scale centre is more suitable as a reference point than the mean value.

- The two major purposes of this paper were: (1) to describe the theoretical background underlying the mathematical development of different measures of the degree of attitudinal polarization applicable to bipolar questions and (2) to outline a small FORTRAN IV program POLARI that provides a rapid means for calculation of four of these measures.
