Tabulation of Data and Types of Tabulation
Tabulation is the systematic arrangement of the
statistical data in columns or rows. It involves the orderly and systematic
presentation of numerical data in a form designed to explain the problem under
consideration. Tabulation helps in drawing the inference from the statistical
figures.
Tabulation prepares the ground for analysis and
interpretation. Therefore a suitable method must be decided carefully taking
into account the scope and objects of the investigation, because it is very
important part of the statistical methods.
Types of Tabulation
In general, the tabulation is classified in two parts,
that is a simple tabulation, and a complex tabulation.
Simple tabulation, gives information regarding one or
more independent questions. Complex tabulation gives information regarding two
mutually dependent questions.
One-Way Table

This table
gives us information regarding one characteristic information about the
population in different divisions of Sindh.
All
questions that can be answered in ONE WAY TABLE are independent of each other.
It is therefore an example of a simple tabulation, since the information
obtained in it is regarding one independent question, that is the number of
persons in various divisions of Sindh in millions.
Two-Way
Table
These types
of table give information regarding two mutually dependent questions. For
example, question is, how many millions of the persons are in the Divisions;
the One-Way Table will give the answer. But if we want to know that in the
population number, who are in the majority, male, or female. The Two-Way Tables
will answer the question by giving the column for female and male. Thus the
table showing the real picture of divisions sex wise is as under:

Three-Way
Table
Three-Way
Table gives information regarding three mutually dependent and inter-related
questions.
For example,
from one-way table, we get information about population, and from two-way
table, we get information about the number of male and female available in
various divisions. Now we can extend the same table to a three way table, by
putting a question, “How many male and female are literate?” Thus the collected
statistical data will show the following, three mutually dependent and
inter-related questions:
1.
Population in various division.
2.
Their sex-wise distribution.
3.
Their position of literacy.

This table
gives information concerning the literacy of both male and female in various
divisions of Sindh. From the table we can explain the sex which has more education
in relation to division, and also, we can say whether literacy is low in rural
areas than in urban areas.
Higher Order
Tables
Higher order
tables are those which provide information about a large number of inter
related questions. Higher order tables may be of four-way, five-way, six-way
etc. Such kind of tables are called manifold tables.
