There are two broad categories of sports statistician: academic statisticians and recorders. If you are an academic statistician, your responsibilities are to track players and team data and analyze this information to develop unique insights about the team, a specific athlete, or the effectiveness of a strategy or tactic. You then make recommendations to team management staff based on your analysis. If you are a recorder, your duties are to record statistics of games in real time. The data you collect provides insights for the team, academic statisticians, and news and media outlets that report on sports.
