Introduction: The collection of data can be classified according to the resemblances and similarities. Classification gives expression to the similarities which may be found in the diversity of individual units. In classification of data units having common characteristic are placed in one class and in this fashion the whole data are divided into a number of classes. Even after classification, the statistical data are not fit for comparison and interpretation and need proper tabulation. The ideal classification should have the characteristics of unambiguous, stability and flexibility. The types of classification are Geographical, Chronological, Qualitative and Quantitative. In this section we shall discuss with Qualitative Data Classification.
