One day her gym teacher assigned her to report the average points earned by women's basketball players in each game in the form of a written report. Then Sergei took 10 player names and their points in one game. He took data from the WNBA AIl-Times Leaders website, based on this data in this regular season Nykesha Sales got 14.2 points per game, Sophia Young-malcolm got 14.3; Kayla McBride got 14.5; DeWanna Bonner got 14.8; Napheesa Collier got 14.9; Sheryl Swoopes got 15.0; Tina Thompson gets 15.1; Jewell Loyd gets 15.2 points; Kelsey Mitchell gets 15.2 points; and Seimone Augustus got 15.4 points.
