Answer:
The Five Factor Model breaks personality down into five components: Agreeableness, Conscientiousness, Extroversion, Openness, and Stress Tolerance. Personality tests that are based on this model measure where an individual lies on the spectrum of each of the five traits.
The five-factor model not only helps people better understand how they compare to others and to put names to their characteristics. It's also used to explore relationships between personality and many other life indicators.
