Class 11 Economics - KERALA
Organisation of Data
Organisation of Data is a crucial chapter in Class 11 Economics under the Kerala SCERT syllabus. It bridges the gap between raw data collection and final data analysis by teaching students how to systematically arrange massive amounts of statistical information. You will learn about classification based on geographical, chronological, qualitative, and quantitative characteristics. The chapter also covers the construction of discrete and continuous frequency distributions, and the rules of tabulation. Mastering this chapter is essential for scoring high marks in board exams, as it forms the foundational base for graphical representation and statistical calculations in later chapters.

Frequently Asked Questions
What is the difference between classification and tabulation?
Classification is the process of arranging data into groups based on common characteristics, whereas tabulation is the subsequent step of presenting this classified data in rows and columns.
What are inclusive and exclusive methods of classification?
In the exclusive method, the upper limit of a class is excluded from that class and included in the next. In the inclusive method, both lower and upper limits are included in the same class.
Why is organization of data necessary before analysis?
Raw data is chaotic and bulky. Organization brings order, highlights significant features, makes comparison easy, and prepares data for graphical or statistical analysis.
