Tabulation is a systematic and logical representation of numeric data in rows and columns to facilitate comparison and statistical analysis. It facilitates comparison by bringing related information close to each other and helps in statistical analysis and interpretation.
In other words, the method of placing organised data into a tabular form is known as tabulation. It may be complex, double, or simple, depending upon the nature of categorisation.
Objectives Of Tabulation:
(1) To simplify complex data
- It reduces the bulk of information, i.e., it reduces raw data in a simplified and meaningful form so that it can be easily interpreted by a common man in less time.
(2) To bring out essential features of data
- It brings out the chief/main characteristics of data.
- It presents facts clearly and precisely without textual explanation.
(3) To facilitate comparison
- The representation of data in rows and columns is helpful in simultaneous detailed comparison on the basis of several parameters.
(4) To facilitate statistical analysis
- Tables serve as the best source of organised data for statistical analysis.
- The task of computing average, dispersion, correlation, etc., becomes easier if data is presented in the form of a table.
(5) To save space
- A table presents facts in a better way than the textual form.
- It saves space without sacrificing the quality and quantity of data.
