===Business and marketing===
; [[Market research]]
:Cluster analysis is widely used in market research when working with multivariate data from [[Statistical survey|surveys]] and test panels. Market researchers use cluster analysis to partition the general [[population]] of [[consumer]]s into market segments and to better understand the relationships between different groups of consumers/potential [[customers]], and for use in [[market segmentation]], [[positioning (marketing)|product positioning]], [[new product development]] and selecting test markets.
; Grouping of shopping items
:Clustering can be used to group all the shopping items available on the web into a set of unique products. For example, all the items on eBay can be grouped into unique products (eBay does not have the concept of a [[Stock-keeping unit|SKU]]).
