This paper provides the key references for, and a summary of, statistical methods for describing and analyzing orientation data. Most of the paper is concerned with the authors approximate analysis of variance procedures for unit vectors in two and three dimensions. They are based on probability density proportional to expkappa cos theta where kappa is an accuracy parameter and theta is the angle between the true and observed directions. A brief account of the theory for expkappa cos sq theta and its generalization is given this may be useful for axial data. Author
