Waterquality {gpk}

Water quality analysis using clustering

Description

Water samples were collected from 4 cities. The physico-chemical properties were measured. It is of interest to compare water in different cities. It is also intended to try cluster analysis after ignoring the city label (are original groups identified?). If water quality is similar then water treatment can be similar.
