Question

The …………. refers to systematic and logical arrangement of data in columns and rows in accordance with some salient features and characteristics.
A) Classification of data
B) Graphical representation
C) Tabulation
D) None of these

Answer 1

Hint:
We will see each option with its definition and then we will determine the correct option for the blank given. Generally rows and columns are in a table. So let’s check!

Complete step by step solution:
Classification of data:
This is the process in which the given data is sorted or is grouped in different categories according to the requirement. This classification can be qualitative or quantitative. But it does not involve any arrangement of data in either rows or columns. So this is not our answer.

Graphical Representation:
In this type the name itself indicates that it uses some graphical features to arrange the data. It uses pictures, shapes or simply lines and dots to represent the data. Various types of graphical representations are bar graph, pie chart, line graph, histogram and frequency table etc. each use different techniques to represent the data. Bar graph and histogram use vertical bars whereas pie charts divide a circle in different slices to represent the data. But neither of them at the end provides arrangement in rows and columns. So this is also not our answer.

Tabulation:
Now this type involves data filling or sorting in the form of rows and columns. There is two way tabulation and three way tabulation apart from normal tabulation. Two ways and three ways have interdependence on each other. But the pattern is rows and columns only.

So the correct option is C.

Note:
All types mentioned above are for arranging the data in a more systematic way. These methods help data analyzers or data readers to go through the data at a single vision.
