typicality
This term describes the extent to which an individual case embodies the defining characteristics of a larger group. It is frequently employed in academic, statistical, and psychological contexts to discuss how well a sample represents a population or how a specific example serves as a prototype for a category. In cognitive science, it refers to the perceived normality of a member within a class, where some members are seen as more central or representative than others. It is an abstract quality and is treated as an uncountable mass noun in these technical applications.
