A successful basket is signaled by a referee raising one arm above their head with an open hand, which clearly communicates to players, coaches, and spectators that the shot has counted. This gesture is standard practice in basketball officiating, providing an immediate visual cue that the scoring play was successful. The raised arm above the head ensures everyone can easily see the signal, particularly in a crowded gym where visual clarity is essential.

Other signals, such as clapping hands or blowing the whistle, are not specific to indicating a successful basket and could confuse players and fans regarding the game's status. Nodding towards the scorer's table, while it may indicate a communication or acknowledgment, does not serve the purpose of signaling a successful score, which is why the open-hand raised signal is the appropriate and established method for this situation.
