Classification and tabulation dr. vijay kumar sbs, su [email protected] fthe collected data in any statistical investigation are usually voluminous, crude in form and are known as raw data. as such they cannot be easily understood by person, and are not directly fit for further analysis and interpretation.

Differences between classification and tabulation of data in classification, information is isolated and gathered in light of a property of the information normal to all qualities. in tabulation, information is orchestrated into sections and lines given attributes properties, or pointers. The primary different between classification and tabulation is that the process of classifying data int groups is known as classification of data whereastabulation is the act of presenting data in tabular form, for better interpretation. after the collection of data is completed, it is prepared for analysis.
