356 cial website, we made an attempt to understand the basic situation of the teams to and carry on data processing. 1.2.2. Video observation method By watching the 2014–2015 season CBA playoffs teams game video, analysis of eight teams offensive and defensive technique features during the regular season and playoffs, we induced and summarized the characteristics of each team and combined with the team game tactics statistic data from CBA professional basketball's official website. 1.2.3. Mathematical statistics method Using the Statistics19.0 of SPSS statistical software, we analized all kinds of technical statistical indexes of 8 teams in 2014–2015 season playoff. 1.2.4. Rank and ratio method (RSR) Rank and analogy method (RSR method for short), is the collection of clas- sical parameters estimation and merits in the integration of modern nonparamet- ric statistics statistical analysis method. The basic idea is in a line of N (N) evaluation object M column (M evaluation index) matrix, the dimensionless sta- tistics were obtained through the rank conversion RSR, of the object can be evaluated by RSR values sorting or step. Calculation method is: RSR = Σ R/(MN), Σ R is generation table indexes rank and value evaluation ob- ject, M is evaluation index number, N is objects evaluation number. RSR values in the range 0-1, the larger value tendency evaluation objects are the best, and vice versa. This research is based on the many years world basketball competi- tion athletes in individual and team technical indicators, such as points, zaid, 3-pointers, free throws, rebounds, assists, blocks, steals, foul, turnovers, viola- tions and so on have demonstrated that samples are normally distributed. Ac- cording to the principle of normal distribution, we chose a 5-grades evaluation method (  +1. 5 s,  +0. 5 s ,  – 0. 5s ,  – 1. 5s ) ， suitable for statistical analysis of basketball game. Basing on RSR research accepted 5 level evaluation standard, we made an analysis of the technical indicators of offence and defense of the 2014-2015 season CBA playoffs teams (table 1). Table 1 (RSR Method) Grade Standard of RSR Comprehensive Evaluation  2-3  Grade Standard A grade B grade C grade D grade E grade Value range above 0.8 0.79 ～ 0.60 0.59 ～ 0.4 0.39 ～ 0.20 less than 0.19 2. Result and analysis 2.1.1. 2014–2015 season CBA playoffs ability of the various teams at- tack, RSR comprehensive evaluation analysis
