Question

What do you mean by “tabulation of data”?

Answer 1

Hint: First explain what is tabulation of data and types of tabulation for different characteristics of data. Give examples for better understanding.

Complete step-by-step answer:
Tabulation of data is the arrangement of data in table and charts. In a table there are two terms to be known, first one is column and second one is row. Rows are horizontal whereas columns are vertical.
Tabulation of data arranges data in an organised way which helps in better understanding of data. It arranges the complex data in statistical and organise manner. Tabulation of data also helps in comparison of sets of data.
Writing down the data in tables converts the data in symmetric arrangement. Classification of tables is based on the categories of data that may have two or more characteristics.
If we collect the data of different cities of India based on their pollution lived in those cities. Then it shows the simple or one-way tabulation of data.
If we collect the data of heights of students of a class on the basis of their gender that is boy and girl, then this type of tabulation of data is known as double tabulation or two-way tabulation.
If there are two or more than two characteristics of data present in a given set of data, then this type of tabulation of data is known as complex tabulation.
Let’s make a table for better understanding. Here is the table made for the average students passed in GK exam of different classes,

Class	Average rate of passing students
V	35
VI	40
VII	33
VIII	45
IX	50

In the above table there are two characteristics which are written in the header that are the class of students and average student passed in the exam. This table helps us to know the result of each class and their comparison with each other in one way.
Note: Tabulation of data arranges the group of data and complex data in an organised manner which helps us in studying and comparing the given set of data.
