Due to the COVID-19 pandemic professional basketball games were played without crowds for the first time. This offered the first opportunity to analyze the home team advantage without the impact of crowd effects. This study aims to identify the direct impact that a home crowd has on the outcome of NBA games. I collected data on every NBA game played from the 2017 to 2018 season through to the 2020 to 2021 season and ran 9 different regressions examining the relationship between crowds and the outcome of the games. However, results showed that the presence of a crowd was not a significant factor in determining the outcome of games but was a significant factor in the scoring rate of games. During the pandemic when games were played without crowds NBA teams scored at a higher rate than when playing in front of crowds. This suggests the home team advantage in the NBA is not attributable to crowd effects.
