Classification and Tabulation

Classification and Tabulation
The data collected for the purpose of a statistical inquiry some times consists of a few fairly simple figures, which can be easily understood without any special treatment. But more often there is an overwhelming mass of raw data without any structure. Thus, unwieldy, unorganized and shapeless mass of collected is not capable of being rapidly or easily associated or interpreted. Unorganized data are not fit for further analysis and interpretation. In order to make the data simple and easily understandable the first task is not condense and simplify them in such a way that irrelevant data are removed and their significant features are stand out prominently. The procedure adopted for this purpose is known as method of classification and tabulation. Classification helps proper tabulation.
“Classified and arranged facts speak themselves, not arranged, unorganized they are dead as mutton”.
