Systematic Presentation of Data:
Generally the collected data is in fragmented form. The mass of data is presented in a concise and simple manner by means of statistical tables.
Thus, tabulation helps in presenting the data in an orderly manner.
Facilitates Comparison of Data:

The presentation of complete and unorganized data in the form of tables facilitates the comparison of the various aspects of the data.

Identification of the Desired Values:
In tabulation, data is presented in an orderly manner by arranging it in rows and columns. Therefore, the desired values can be identified without much difficulty. In the absence of tabulated data, it would be rather difficult to locate the required values.
Provides a Basis for Analysis:
Presentation of data in tabular form provides a basis for analysis of such data. The statistical methodology suggests that analysis follows presentation of data.
A systematic presentation of data in tabular form is a prerequisite for the analysis of data Statistical tables are useful aids in analysis.

Exhibits Trend of Data:
By presenting data in a condensed form at one place, tabular presentation exhibits the trend of data. By looking at a statistical table, we can identify the overall pattern of the data.
