Amanda ends up getting the same grade as the other group members. This is an example of Social Loafing.
Explanation:
When people work in group, the individuals usually exert less effort as compared to the effort they put if they work alone. This phenomenon is called as the Social Loafing.
In Social Loafing, people working in groups are more dependent upon others and feel less responsibility of work. They share less efforts and seek equal reward. That is why, group's efficiency is usually seen low.
