Final answer:
The team's scores are in the 3rd quartile, meaning they score more points than at least 75% of all teams, placing them in the top 25%.
Step-by-step explanation:
If the points scored per game by a volleyball team represent the 3rd quartile of all teams in a league, we can conclude that the volleyball team consistently scores more points than most teams in the league. The third quartile is a statistical term that refers to the value below which 75% of the data falls. This means that the team's points per game are higher than at least 75% of all other teams' scores, placing them in the top 25% of the scoring distribution.
