Sheldon (1940) examined the relationship between personality characteristics and physical characteristics (body shape). He identified three categories of body shape: endomorph, ectomorph, and mesomorph, corresponding to rounded, thin, and muscular, respectively. He then evaluated personality characteristics that tend to be associated with each body type. One relationship Sheldon examined involved sociability and body type. Specifically, endomorphs tend to be more social, and ectomorphs tend to be more private. The following hypothetical data represent an attempt to demonstrate this relationship. Sociability scores were obtained for three separate samples representing the three different body types.
