The 2020 NBA playoffs were played inside of a bubble in Disney World because of the COVID-19 pandemic. This meant that there were no fans in attendance, games played on neutral courts and no traveling for teams, which in theory removes home-court advantage from the games. This setting has attracted much discussion as analysts and fans debated the possible effects it may have on the outcome of games. Home-court advantage has historically played an influential role in NBA playoff series outcomes. The 2020 playoff provided a unique opportunity to study the effects of the bubble and home-court advantage by comparing the 2020 season with the seasons in the past. While many factors contribute to the outcome of games, points scored is the deciding factor of who wins games, so scoring is the primary focus of this study. The specific measures of interest are team scoring totals and team shooting percentage on two-pointers, three-pointers, and free throws. Comparing these measures for home teams and away teams in 2020 vs. 2017-2019 shows that the 2020 playoffs favored away teams more than usual, particularly with two point shooting and total scoring.
翻译：2020 NBA 决赛在迪士尼世界的泡沫中进行,原因是COVID-19大流行,这意味着没有球迷在场,没有球迷在中立的法庭上玩游戏,没有球队旅行,理论上从游戏中排除了家庭法院的优势。这一场景吸引了许多讨论,因为分析家和球迷们辩论了球队可能对游戏结果产生的影响。在NBA决赛系列成果中,家庭法院优势历来发挥了有影响力的作用。2020年决赛提供了一个独特的机会,通过比较2020年赛季和过去赛季来研究泡沫和法院优势的影响。虽然许多因素促成了游戏的结果,但得分是谁赢得比赛的决定性因素,因此得分是本项研究的主要重点。具体的兴趣措施是团队评分总数和两分球队射击的百分比、三分球队和免费投球。在2020年和2017-2019年对家球队和离队的这些措施进行比较,显示2020年的决赛场比通常更有利于球队,特别是两分射击和全分。
