On page 279, Rencher says concerning this data: The data were collected by G. R. Bryce and R. M. Barker (Brigham Young University) as part of a preliminary study of a possible link between football helmet design and neck injuries.  Six head measurements were made on each subject.  There were 30 subjects in each of the three groups.
