NCERT Solutions For Class 11 Statistics Chapter 4 Presentation Of Data - 2025-26

Chapter 4 in this section, is the Presentation of Data. NCERT solutions for class 11 statistics for economics chapter 4 is also available, which covers every topic of the concerned chapter.

Data Can Be Represented In Two Forms. They Are As Follows

• Textual Presentation

• Tabular Presentation

• Diagrammatic Presentation

In a textual presentation of data, data form a part of the text or description pf the subject matter. The tabular presentation of data, on the other hand, shows a systematic presentation of numerical data. The tabular presentation includes various components. They are:

• Title

• Headnote

• Caption

• Table number

• Body or field

• Footnotes

• Source

• Stubs

Under diagrammatic presentation, bar diagrams are one of the most popular types of data presentation. Different types of bar diagram are:

1. Simple Bar Diagram

2. Multiple Bar Diagram

3. Percentage Bar Diagram

4. Sub Divided Bar Diagram

All of the above topics have been serially detailed in NCERT solutions class 11 statistics chapter 4. The 15 questions included in this chapter provide a proper insight into “Presentation of Data’.

Questions Given in the NCERT Solutions for Class 11 Statistics for Economics Chapter 4

Each question in the NCERT solutions is followed by a precise, appropriate, and relevant answer. The answers which are given in the solution also follow the CBSE pattern of the exam. This helps students get a brief idea regarding the types of questions they might face in the final exams. Here’s a gist of all the questions included in the Statistics class 11 NCERT solutions chapter 4:

Question 1: The very first question in this chapter of NCERT solution is regarding bar diagrams. The question asks whether the bar diagram is a one-dimensional, two-dimensional or non-dimensional diagram. Bar diagrams are single-dimensional. Although it contains two axes in the form of rectangular bars, the width plays no role in data presentation. Only length plays a part in bar diagrams.

Question 2: The second question NCERT solutions for class 11 statistics for economics chapter 4 is directed towards histograms. It asks students the use of histograms. Histograms are used to represent the value of mode of frequency distribution through graphs with the help of the highest rectangle.

Question 3: The third question is regarding ogives. It asks if ogives can be helpful in graphically locating the mean, mode, or median. The answer to this question would be ‘median’. The point of intersection of more than and less than ogives shows the median of data.

Question 4: The 4th question is NCERT solutions class 11 statistics chapter 4 asks what data represented through arithmetic line graph depict. The options in this question include ‘long-term trend’, ‘cyclicity in data’, and ‘seasonality in data’. Arithmetic line graph assists in understanding the periodicity and trend observed in long-term continuous data.

Question 5: The 5th question is based on a true/false statement. The statement given is whether the width of bars in a bar diagram can be unequal. This statement is, however, false. The rectangular bars in a bar diagrams need to be of equal width for any given data.

Question 6: The statement given in this question is ‘Width of rectangles in a histogram should essentially be equal’. It is a false statement. The width of rectangles in a histogram can be uneven.

Question 7: Here, the statement in question is ‘Histogram can only be formed with a continuous classification of data’. This is a true statement. Histograms are always drawn for continuous data. Even if the given data is discrete or discontinuous, it is first changed into continuous form to form a histogram.

Question 8: The statement in this question is Histograms and column diagram are a similar way of presentation of data. However, this is a false statement. The histogram is a two-dimensional diagram which is drawn for continuous data. The rectangles do not have any space between them. On the other hand, the column diagram is a one-dimensional diagram which has space between each column or bar. 

Question 9: The 9th question has ‘Mode of a frequency distribution can be known graphically with the help of histogram’ as a statement. This statement in NCERT solutions for class 11 statistics for economics chapter 4 is true. The rectangle with the highest measure in a histogram gives the value of mode of a frequency distribution. 

Question 10: The statement given in this question is that the median of a frequency distribution cannot be assessed from the ogives. This is false. The point of intersection of less than along with more than ogives shows the median.

Question 11: The 11th question in this chapter asks students to provide relevant forms of diagrams to represent different data. There are three sub-parts to this question. They are:

• Monthly annual rainfall

• Composition of Delhi’s population by religion

• Components of the factory’s expenses

The relevant answers to the above questions are bar diagram, component bar diagram, and a pie chart respectively.

Question 12: This question in NCERT solutions for class 11 statistics for economics chapter 4 would require students to represent data in a tabular form. The question provides data related to the share of non-workers and lower urbanisation level in India.

Question 13: The 13th question is how the procedure of drawing histograms differ when class intervals are unequal compared to equal class intervals in a frequency table.

Question 14 and Question 15 also include data, based on which students will have to form a relevant presentation.
