5) The NBA is interested in the proportion of players from 1998-2018 who have received concussions while playing. They believe that as time goes on, the game is changing and the concussion percent may be higher than it once was. A study from 1978-1998 stated that the proportion of players who received a concussion while they played was .56. When they conducted a study of 4200 players who played in the NBA or G-League during 1998-2018, they found that 2436 received a concussion while playing. If the NBA can find evidence at an α=.006 level that the proportion of concussions from 1998-2018 is higher than the proportion of concussions from 1978-1998, the NBA will change some rules to keep the players safer.
