Abstract
In This paper the cluster analysis technique (The Euclidean Separation Distance Coefficients) is used to test the membership of individuals in groups of galaxies and apply specific criteria to identify the members which should be excluded from these groups. The method is applied to quintet galaxy groups taken from final release of the two degree field galaxy redshift survey (2dFGRS) . The sample included 4739 quintets with total number of 23695 galaxies. The final results indicate that 317 Groups have one galaxy that has attribute discordant and should be discarded from its grou p.
