Abstract
Many stores-style exists so that it is said a characteristic an item to treat at each store as for the no mark quality goods to handle many items. However, in this study, I performed cluster analysis and investigated validity of the store-style of the no mark quality goods to confirm it whether those stores-style did not have to think about one or other stores-style made use of. In addition, using association rule analysis, I investigated whether even the cluster was different in the simultaneous purchasing of the product which I purchased. It is thought that this difference is useful for the sales strategy in the cluster.
