Document Summary
Factor analysis allows the researcher to reduce many specific traits into more general factors or groups of traits, each of which combines several of the specific traits. Allows us to summarize the relations among a large number of variables in terms of only a small number of groups, or factors. The factors that are produced by this technique should be thought of as dimensions along which people differ, and not as types of people. The existing list of important personality traits can be found in the dictionary. Galton (1884) noted that the various personality-descriptive words listed in the dictionary would overlap and blend into each other, with each word partly sharing its meaning with other words, and partly having some unique meaning of its own. Raymond cattell was the first to do a factor analysis of ratings on personality-descriptive adjectives in english: set of 35 variables.
