Statistical Analysis Methods of the Data Obtained by Water Electro Conductivity Measurement

Abstract

The distilled water investigation has been undertaken by means of the descriptive and correlation method analysis backed by the Statistica and Matlab software. The conclusion has been made that further investigation to study chemical properties of water and water solutions is needed. The paper presents a method exploring the water properties measuring results by means of the professional water quality measurement meter WMM-97 at the temperature of 21°С and water pH (pH of the media corresponded to the State Standards 58144 5.0-6.6). The distilled water electro conductivity has been measured within a one-week time-period (the electro conductivity being in compliance with the State Standards 58144, less than 0,43 mCm/m), the indicators being registered each second.
