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
DIVISION

Karachi
Hyderabad
Sukkur
POPULATION
(Millions)
10.875968
14.186954
12.994401

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:
TWO-WAY TABLE
DIVISION
POPULATION (Millions)
Male
Female
Total
Karachi
Hyderabad
Sukkur




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.
THREE-WAY TABLE
DIVISION
POPULATION (Millions)
Male
Female
Total


Karachi
Hyderabad
Sukkur
Literate
Illiterate
Total
Literate
Illiterate
Total
Literate
Illiterate
Total
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.

Nothing is Impossible in the World (Essay)

When we takes up many things in hand and fail in the most of them we bewail our lot and try to console by saying that we were fated to achieve this and fail in that. But fate is a figment of man’s imagination, it is refuge only for those who are cowardly and lack in determination. Because nothing is impossible in the world. Man is architect of his own fate. He can make himself if he has the will. He can also mar himself if he wavers and submits to opposing forces. A man of determination never fails. His unshaken determination coupled with this unflinching endeavour carries him to the goal and makes him thoroughly successful man. But a man who trembles of every step and has no confidence in himself, can never reach the goal and dies an inglorious death. Robert Bruce could never have regained his mother land from clutches of the enemy if he submitted to the so called fate and gave up the attempts. If Mahmood Ghaznavi has lost the hope, he could not have conquered the Somnath temple
