Basic Knowledge
Divide by Team Count or by Number of People
There are two approaches to team division: deciding the number of teams and assigning everyone to them, or deciding the number of people per team and creating as many teams as needed. The first method works better for sports with a fixed number of courts, while the second is better for events where team capacity is predetermined.
Fairness in Random Division
Shuffling by random number does not account for skill level, age, or personal relationships, but it has the advantage that no one's intent is involved, which creates a sense of fairness. The more a situation tends to generate dissatisfaction with how decisions are made, the more effective random division's fairness becomes.
