Class 11 Economics - HARYANA
Organisation of Data
The chapter 'Organisation of Data' in Class 11 Economics bridges the gap between raw data collection and data analysis. Students learn how to edit, classify, and tabulate data systematically to make it comprehensible. Key topics include the basis of classification (chronological, spatial, qualitative, and quantitative), variables (discrete and continuous), and the components of statistical tables. This chapter is vital for Haryana (BSEH) board exams as it forms the foundation for graphical presentation and mathematical calculations of measures of central tendency, frequently appearing in both objective and short-answer sections.

Variables
A characteristic or phenomenon that can take on different quantitative values, categorized into discrete variables (exact values) and continuous variables (within a range).
Frequency Distribution
A tabular summary of data showing how frequently each of the given values or categories occurs in the dataset.
Tabulation

Board Exam Info
In the Haryana (BSEH) Class 11 Economics board examinations, this chapter typically carries around 6 to 8 marks. Common question types include short-answer questions on the objectives of classification, numerical problems on converting inclusive series to exclusive series, and long-answer questions detailing the essential parts of a statistical table.
Frequently Asked Questions
What is the difference between classification and tabulation?
Classification is the process of arranging raw data into groups according to common characteristics, whereas tabulation is the final step of presenting this classified data in an organized table of rows and columns.
When should we use an inclusive series instead of an exclusive series?
An inclusive series is generally used when dealing with discrete variables (like number of children or shoe sizes) where decimal fractions are not involved, whereas exclusive series is preferred for continuous variables.
How do you calculate the mid-value of a class interval?
The mid-value is calculated by adding the lower limit and upper limit of a class interval together and dividing the sum by 2.
