Statistical analysis of base basketball: Under-17 Parana men Basketball Championship profile

It has as its general objective, describe how is the logic of dynamic from base basketball games. Specifically, it sought to understand which are the statistical indicators meaningful to claim victory in the game and competition in general and in balanced, normal and unbalanced games; which is the influence of the indicator "efficiency" individual and collective for the end result of game and competition; and which is the relationships between the momentum of the game with the same results. The methodology used the descriptive quantitative research, with a statistical analysis spreadsheet built specifically for research as an instrument. The data processing was through descriptive and inferential statistics. Results: 2 points attempts, 2 points converted, 2 points percentage, total points made, overall hit percentage, defensive rebounds, total rebounds and assists were considered significant for obtaining victory in the game. The same indicators, plus "free throws attempted" were coincident in balanced, normal and unbalanced games. 2 points attempts, 2 points converted, 2 points percentage, overall hit percentage and offensive rebounds were significant for achievement of victory in the competition. Teams that won the game and competition presented collective efficiency superior to others. An average of 4 players per team presented individual efficiency higher than the average of individual efficiency of the team and competition. The second and last quarters were even more relevant for obtaining the victory in the game and the competition. In conclusion, it is understood that the statistical analysis is a relevant source of information on a basketball game, and can provide relevant insights for researches and technical committees.

本数据集的总体目标为阐释基础篮球赛事的动态运作逻辑。具体而言，研究旨在明确可用于判定赛事及整体竞技胜负的有效统计指标，并针对均衡赛事、常规赛事与非均衡赛事分别展开分析；探究个体与集体的“效率（efficiency）”指标对赛事及竞技最终结果的影响；以及剖析赛事走势与比赛结果之间的关联关系。本研究采用描述性定量研究范式，定制专用统计分析表格作为研究工具，数据处理环节运用描述性统计与推断性统计分析手段。研究结果表明：两分球出手次数、两分球命中次数、两分球命中率、总得分、整体投篮命中率、防守篮板数、总篮板数以及助攻数，均为影响赛事胜负的显著统计指标。在均衡赛事、常规赛事与非均衡赛事中，除上述指标外，罚球出手次数也与赛事胜负显著相关。针对整体竞技胜负而言，两分球出手次数、两分球命中次数、两分球命中率、整体投篮命中率以及进攻篮板数为关键显著指标。最终赢得赛事及整体竞技的球队，其集体效率显著高于其他球队。平均而言，每支球队中有4名球员的个体效率高于球队及整体竞技的个体效率平均值。赛事的第二节与末节，对赢得赛事及整体竞技的影响更为关键。综上可见，统计分析可为篮球赛事提供极具价值的信息依据，亦能为相关研究及技术委员会提供重要参考见解。
