Stability Coefficient

The stability coefficient is a measure used to assess how consistently a particular trait or characteristic remains over time or across different situations. For example, in psychology or education, it indicates whether a person's behavior, skills, or attributes are reliably similar in various contexts or periods. A high stability coefficient suggests that the trait is stable and predictable, while a low coefficient indicates more changeability or variability. It helps researchers and practitioners understand whether observed differences are due to genuine change or just measurement noise.
