title: Remarks on the Study of the Variety of Individuals.
abstract: Techniques for the study of the variety of individuals are discussed. A contrast is pointed out between the study of mean performances and the study of covariations. These are two components of the performances of the individuals. For the study of the variety of individuals, instead of keeping these two components separate, these two components should be combined into a single analysis. Examples of techniques which combine these two components are discussed.
