In this paper we extract the cluster by using numerical as well as statistical methods for improving efficiency using efficient algorithms of k-means in data mining. So, Data mining is defined as finding hidden information in a database it has been called exploratory data analysis, data driven discovery, and deductive learning.[1] clustering is usually accomplished by determining the similarity among the data on predefined attributes. The most similar data are grouped into clusters. This paper proposes a method for making the k-means algorithm and Bisection method for more effective and efficient, so as to getting better cluster.
