A Dispersion Analysis of the Interests of 115 Occupational and Reference Groups

摘要

In general, therefore, the dispersion analysis model employed yields results which summarize the relations among the groups studied in a sensible and meaningful way. The chief deficiency of the set of homogeneous keys was in their failure to separate the various mechanical and electrical occupations from each other.nIt was found that about 80 percent of the among-groups variance can be accounted for by the four best linear functions, and the best six out of nine extract almost 92 per cent of the intergroup information. Thus fewer than half the total number of canonical variates are needed to effect a fairly accurate reconstruction of the space.
