Difference between Classification and Tabulation
• The data are classified before they are put in tables.

• The process of classification begins when the
process of collection ends whereas the process of
tabulation begins when the process of classification
ends.
• In the process of classification data are arranged
according to attributes and variables, whereas in the
process of tabulation data are arranged in columns
and rows.



Difference between Classification and Tabulation…

• The classification process refers to the arrangement
of data into classes or groups, whereas the tabulation
process refers to the placement of data in a tabular
form. One refers to the identification of data and the
other presentation of data.

• To facilitate the data for a comparative study

• To clarify the characteristics of data.




Importance or Advantages of Tabulation

• It simplifies complex data and the data presented are
easily understood.

• It facilitates comparison of related facts.

• It facilitates computation of various statistical measures
like averages, dispersion, correlation etc.

• It presents facts in minimum possible space and
unnecessary repetitions and explanations are avoided.
