“…There are many methods to measure these variations, and no single method should be regarded as most appropriate [8]. The withinseason, competitive balance has been evaluated for a number of individual or team sports, including baseball, basketball, football, ice hockey, soccer, speed skating, table tennis, and tennis using the Herfindahl-Hirschman Index (HHI), Competitive Balance Ratio (CBR), the ratio of standard deviations (RSD), Gini coefficient and related Lorenz curve, relative entropy, and other, specific-sport-based criteria, such as points, scores, or time [10][11][12][13][14][15][16][17][18][19][20][21][22]. Between-seasons variation can be evaluated for an individual team using the team-specific variation in standing in different seasons (turnover) [11], or by measuring the concentration of championships in a given time period [8].…”
