1. Multiple choice questions.

Q1. Which of the following is not a method of presenting data?

• (a) Tabular presentation
• (b) Diagrammatic presentation
• (c) Musical presentation
• (d) Textual presentation

Answer: (c) Musical presentation. Only textual, tabular, and diagrammatic presentations are recognized methods in statistics.

Q2. What kind of classification is used when data are grouped based on place?

• (a) Temporal classification
• (b) Spatial classification
• (c) Qualitative classification
• (d) Quantitative classification

Answer: (b) Spatial classification. Spatial relates to data classified according to locations or places.

2. Very Short Answer (VSA).

Q3. Define tabular presentation of data.

Answer: Tabular presentation means arranging data systematically in rows and columns, making them easy to read, compare, and analyze.

Q4. What is a component bar diagram?

Answer: A component bar diagram displays data for multiple related variables in a single bar by dividing it into proportional components.

Q5. How is a temporal classification done?

Answer: Temporal classification organizes data according to time periods, such as years, months, or days.

3. Short Answer Questions.

Q6. Briefly distinguish between textual and tabular presentation of data.

Answer: Textual presentation describes data through sentences within the text, suitable for limited data. Tabular presentation arranges data in rows and columns, allowing for easy comparison, classification, and further analysis, especially when handling larger datasets.

Q7. How does diagrammatic presentation of data help in understanding information?

Answer: Diagrammatic presentation converts data into visual forms like charts and graphs. This makes complex data easier to interpret, helps in identifying trends and comparisons quickly, and enhances comprehension for all types of readers.

Q8. List two essential components of a good statistical table.

Answer: Two essential components are: (1) Title – giving clear understanding of the data's content, and (2) Captions or column headings – which describe the data presented in each column for easy reference.

4. Long Answer Questions.

Q9. Describe the steps involved in constructing a statistical table and explain the importance of each part.

Answer: Constructing a statistical table involves several essential steps. First, assign a table number and a concise title for identification and clarity. Then, add captions as column headings and stubs as row headings. The body contains the main data. Specify the unit of measurement, indicate the data source at the table's bottom, and include notes for any specifics. Each part ensures the table is clear, precise, and facilitates easy understanding and accurate interpretation of data.

1. Assign table number and title.
2. Add captions (column headings) and stubs (row headings).
3. Enter the body (main data) at intersections.
4. Mention units and rounding details if any.
5. State the source of data and add explanatory notes if needed.

Q10. Analyze the advantages and limitations of diagrammatic versus tabular data presentation, using examples from the chapter.

Answer: Diagrammatic presentations, like bar diagrams and pie charts, make data highly visual and easy to grasp trends or comparisons swiftly. For example, a pie diagram easily shows the share of various categories. However, they may not always reveal precise values. Tabular presentation, on the other hand, systematically organizes extensive data, facilitates exact quantitative analysis, and supports further statistical computation but may overwhelm some users. Both forms should be chosen as per the audience's needs and data complexity.

1. Visuals (diagrams) aid quick communication.
2. Tables support detailed calculations and multiple comparisons.
3. Choice depends on user and purpose.

5. Assertion–Reason type questions.

Assertion (A): Pie diagrams are effective in displaying parts of a whole.
Reason (R): In a pie diagram, each sector’s angle is proportional to the corresponding quantity.

• (a) A and R are true, and R is the correct explanation of A
• (b) A and R are true, but R is not the correct explanation of A
• (c) A is true, but R is false
• (d) A is false, but R is true

Answer: (a) Both statements are true and R explains why pie diagrams effectively represent part-to-whole relationships.

6. Case-based questions.

A school surveyed 50 students about their favorite news channels. The data was presented in a two-column table categorizing students by channel names. Soon after, a teacher displayed the same data in a bar diagram during assembly to make the results clearer for everyone.

(i) Which forms of data presentation were used in this situation?

Answer: Tabular and diagrammatic (bar diagram) presentations were used.

(ii) Why did the teacher choose a bar diagram for the assembly?

Answer: To make the data visually clear and quickly understandable to a large audience.

(iii) Mention one advantage of tabular presentation noticed during the survey.

Answer: It helped organize and compare preferences easily between channels.

7. Match the following.
