Abstract (2. Language): 
The purpose of this study is to compare and to evaluate performance of the teams in Turkish Beko Basketball League in term of efficiency rating for the last three seasons. The efficiency rating of teams was calculated using the statistical data of the teams (n=16) of the Beko Basketball League that competed in 2006-2007, 2007-2008 and 2008-2009 seasons. Efficiency rating of the teams was compared using one-way analysis of variance (ANOVA) according to seasons. Significant effects were analyzed using the Bonferroni for the Post Hoc. The level of significance was set at 0.05. There was a significant difference between the efficiency rating of basketball teams in terms of seasons (F(2,45)=4.10, p<0.05). When compared, there was no difference (p>0.05) between the efficiency rating for 2006-2007 season ( =66.12±7.66 score) and the efficiency rating for 2007-2008 season ( =72.06±7.05 score). However, the efficiency rating for 2006-2007 season ( =66.12±7.66 score) was significantly lower (p<0.05) than the efficiency rating for 2008-2009 season ( =72.93±7.20 score). Meanwhile, there was no significant (p>0.05) difference between the efficiency rating for 2007-2008 season and the efficiency rating for 2008-2009 season. As a result of this study, it was determined that the efficiency of the Beko Basketball League in 2008-2009 season was higher than 2006-2007 and 2007-2008 season. The concept of the efficiency rating used in this study can be thought to be directed to a new approaches.
Abstract (Original Language): 
Bu çalışmanın amacı, Türkiye Beko Basketbol Ligi’nde oynayan takımların son üç sezon performanslarını verimlilik puanı ile değerlendirmek ve karşılaştırmaktır. Toplam 16 takımdan oluşan Beko Basketbol Ligi takımlarının verimlilik puanı 2006- 2007, 2007-2008 ve 2008-2009 sezonu istatistikleri kullanılarak hesaplanmıştır. Takımların sezonlara göre verimlilik oranları tek yönlü varyans analizi (ANOVA) ile karşılaştırılmıştır. İkili karşılaştırmalar Bonferroni testi kullanılarak analiz edilmiştir. Anlamlılık düzeyi % 5 olarak kabul edilmiştir. Sezonlara göre basketbol takımlarının verimlilik oranları arasında anlamlı fark bulunmuştur (F(2,45)=4.10, p<0.05). Sezonlar arası farkların ikili karşılaştırması yapıldığında, 2006-2007 sezonu verimlilik puanı ( =66.12±7.66 puan) ile 2007-2008 sezonu verimlilik puanı ( =72.06±7.05 puan) arasında anlamlı bir fark bulunmamıştır (p>0.05). Ancak, 2006-2007 sezonu verimlilik puanı ( =66.12±7.66 puan), 2008- 2009 sezonu verimlilik puanından ( =72.93±7.20 puan) anlamlı düzeyde düşük bulunmuştur (p<0.05). 2007-2008 sezonu ile 2008-2009 sezonu verimlilik oranları ise birbirine benzer bulunmuştur (p>0.05). Bu çalışmanın sonucunda Beko Basketbol Liginin 2008-2009 sezonu verimliliğinin 2006-2007 ve 2007-2008 sezonundan daha yüksek olduğu belirlenmiştir. Bu çalışmada kullanılan verimlilik puanı kavramının yeni yaklaşımlara yönlendirici olacağı düşünülebilir.
