This document discusses different methods of presenting statistical data, including textual, tabular, and diagrammatic presentation. It defines key terminology used in statistical analysis like variables, frequency, class intervals, and distributions. Different types of statistical tables like simple one-way tables and double two-way tables are described. Common diagrams for presenting quantitative data are explained, including simple bar diagrams, sub-divided bar diagrams, multiple bar diagrams, and pie charts. Types of graphs like histograms, frequency polygons and ogives curves are also outlined.

Tabular presentation
Diagrammatic presentation.

6. Textual
Presentation

8. Example 2
• In a bandh call given on 08 September 2005 protesting the hike in
prices of petrol and diesel, 5 petrol pumps were found open and 17
were closed whereas 2 schools were closed and remaining 9 schools
were found open in a town of Bihar.

9. Example 3
• For example, “the 2002 earthquake proved to be a mass
murderer of humans. As many as 10,000 citizens have been
reported dead”.

10. TABULAR PRESENTATION

11. The analysis used in tabulation is of
four types
Qualitative Quantitative Temporal Spatial

12. Objectives of
Tabulation
To present the data in a simple
and understandable manner
To facilitate comparison of data
To provide a bird’s eye view of
the entire data
To facilitate quick location of
required data

24. Frequency Distribution

25. Frequency Distribution Meaning
• Frequency distribution is summary
presentation of values of variable
according to their magnitude
individually or in groups.

27. Basic Terminologies under Frequency
Distribution
• CLASS INTERVAL
• CLASS LIMITS
• INCLUSIVE CLASS INTERVAL
• EXCLUSIVE CLASS INTERVAL
• MID-VALUE
• CLASS FREQUENCY
