Organisation of Data
- Classification: Grouping raw data into categories (e.g., age groups, income levels).
- Tabulation: Arranging data into tables for easy comparison and analysis.
Presentation of Data
- Textual Presentation: Explaining data in sentences or short paragraphs.
- Tabular Presentation: Showing information in rows and columns (Tabulation).
- Diagrammatic/Graphical Presentation: Using bar graphs, pie charts, histograms to make trends visible (Presentation of Data MCQ).

FAQs on MCQs on Collection, Organisation and Presentation of Data
1. What is the collection, organisation and presentation of data?
Collection, organisation, and presentation of data is a systematic process in statistics and economics. It involves gathering raw data, arranging it logically, and displaying it effectively using various methods for analysis and decision-making. This is crucial for understanding Class 11 Economics Statistics.
2. What are primary and secondary data? (MCQ context)
Primary data is original information collected firsthand for a specific purpose, while secondary data is pre-existing information obtained from sources like published reports or databases. Understanding the difference between these data types is key to answering MCQs on data collection in Class 11 Economics.
3. What’s the difference between tabular and diagrammatic presentation of data?
Tabular presentation arranges data in rows and columns, suitable for detailed information. Diagrammatic presentation uses charts (like bar graphs, pie charts) and graphs to visually represent data, highlighting trends and patterns more effectively. Both are important data presentation methods for Statistics.
4. Why is organizing raw data important?
Organizing raw data transforms unstructured information into a meaningful format. This facilitates analysis, reduces errors in interpretation, and allows for effective data presentation in various forms such as tables and diagrams for Class 11 Economics exams.
5. Where can I access Class 11 Statistics Chapter 4 MCQ online tests?
Vedantu provides Class 11 Statistics Chapter 4 MCQ online tests and downloadable resources to aid exam preparation. These resources help students practice MCQs on collection, organisation and presentation of data.
6. What is data collection mcq?
A data collection MCQ (multiple-choice question) tests your understanding of methods for gathering information, such as surveys, experiments, and observations. Knowing the different types of data (primary and secondary) is vital for answering these questions accurately.
7. What is a collection of related data mcq?
A collection of related data in an MCQ context might refer to a dataset. The question could test your understanding of how such datasets are organized and presented to facilitate analysis for Class 11 Economics.
8. What is the collection organization presentation and analysis of data?
The process involves data collection (gathering information), data organisation (arranging it systematically), data presentation (displaying it using tables, charts, etc.), and data analysis (interpreting the presented data to draw conclusions). This is a fundamental process in statistics and economics.
9. Which of the following statements correctly describes the process of classifying raw data?
Classifying raw data involves grouping similar data points into categories for easier analysis and presentation. This could include sorting by type (primary/secondary), numerical range, or qualitative characteristics. Understanding data classification is crucial for NCERT/CBSE exams.
10. How do data classification and tabulation improve economic decision-making?
Data classification and tabulation help economists identify trends, patterns, and outliers within datasets. This supports more accurate, evidence-based conclusions in economic analysis and improves decision-making in business and policy.
11. What are common mistakes students make in MCQ questions on data organization?
Common mistakes include confusing primary and secondary data, misinterpreting data classification terms, or overlooking differences between tabular and diagrammatic presentation. Careful review of definitions and practice with MCQs is key to avoiding these errors.
12. How do examiners frame tricky MCQs on data presentation?
Tricky MCQs on data presentation often include similar-looking answer choices, subtle differences in presentation types (e.g., bar chart vs. histogram), or real-life data collection scenarios requiring careful analysis. Practice with diverse question types helps build resilience.
