Final answer:
Generalization is used to simplify models of a system with many similar objects by replacing the real system with a simpler representation. This allows scientists to study the simplified model and gain insight into the real system.
Step-by-step explanation:
Generalization is used to simplify the models of a system with many similar objects by replacing the real system with something similar but easier to examine. This allows scientists to study the simplified model and gain a better understanding of how the real system works. For example, when studying the behavior of a large population of animals, scientists may create a model using a smaller, more manageable group of animals that share similar characteristics.
