Class 11 Economics - ODISHA
Organisation of Data
The chapter 'Organisation of Data' in Class 11 Economics for Odisha BSE students focuses on the systematic arrangement of raw data into a readable and understandable form. Once data is collected, it must be organized before analysis can begin. This chapter covers the classification of data based on characteristics such as qualitative and quantitative attributes, the concept of variables, and the creation of discrete and continuous frequency distributions. Understanding this chapter is crucial for board exams as it forms the foundational step for constructing tables and graphical presentations, which frequently appear in both short-answer and long-answer questions.

Organisation of Data
The process of arranging raw, unorganized data into coherent classes or groups based on common characteristics to make it ready for analysis.
Classification
The method of dividing a large mass of heterogeneous data into homogeneous groups or classes according to their common properties.
Variable
A characteristic or phenomenon that can take on different numerical values, such as height, weight, income, or marks.
Frequency Distribution
A table that shows how often each different value or range of values occurs in a data set.
Exclusive and Inclusive Series
Exclusive series includes the lower limit but excludes the upper limit, whereas inclusive series includes both lower and upper limits in the same class interval.

Frequently Asked Questions
What is the difference between raw data and organized data?
Raw data is the initial, unorganized collection of facts and figures, while organized data is systematically arranged in rows and columns or frequency tables for easy understanding and analysis.
When should we use an inclusive series instead of an exclusive series?
An inclusive series is generally used when data consists of discrete whole numbers where decimal values are not expected, whereas an exclusive series is preferred for continuous variables like height, weight, and time.
How do we calculate the mid-point of a class interval?
The mid-point is calculated by adding the lower limit and upper limit of a class interval and dividing the sum by 2.
