Final answer:
Mediation involves a third party, while negotiation is direct.
Step-by-step explanation:
The difference between mediation and negotiation is that mediation involves a third party, while negotiation is direct. In mediation, the third party acts as a neutral facilitator who helps the parties involved in a conflict come to a resolution. On the other hand, negotiation is a direct discussion between the parties themselves, without the involvement of a third party.
