The performance of the counters data

Description

A water supply company wants to control the performance of the water counters installed throughout a city. For this purpose, 60 rational samples have been taken, each one composed by 3 measurements, from the same age (10 years) and caliber water counters corresponding to two different brands, and during a period of 5 years. This dataset is based on a study case of A Coruña’s water supply company, Empresa Municipal de Aguas de La Coruña (Emalcsa).
