waterquality


Water
samples from four cities are collected and their physico-chemical properties for ten variables, such as <code>pH</code>, <code>Conductivity</code>, <code>Dissolution</code>, etc., are measured. We would then like to test if the properties are same across the four cities and in which case a same water treatment approach can be adopted across the cities.
