Presentation of Data — Textual and Tabular Methods
Once data have been collected and classified, the next job is to show them. NCERT identifies three forms of presentation — textual, tabular and diagrammatic. This part walks through the first two: how data hide inside the running text of a paragraph, why a serious researcher prefers a table, and what the eight precise parts of a good statistical table really mean. Along the way we re-build NCERT's literacy table, the Bihar election table, the yearly tea-shop sales and the India exports table.
4.1 Why Presentation Matters
In the previous chapters you learnt how data are collected and organised. The honest difficulty is that raw data are voluminous — page after page of numbers that nobody can read at a glance. The whole point of presenting data is to compress them into a compact, comprehensible form so that a reader can pick up the main message in a few seconds.
NCERT lists three standard methods of presentation. We will study textual and tabular presentation here, and diagrammatic presentation in Part 2.
4.2 Textual / Descriptive Presentation
In textual presentation?, the figures are simply embedded in the sentences of a paragraph. The reader has to wade through the prose to extract the numbers. NCERT illustrates this with two cases — a small one (a Bihar bandh count) and a much heavier one (Census 2001 totals).
In a bandh call protesting the hike in petrol and diesel prices, 5 petrol pumps were found open and 17 were closed, while 2 schools were closed and 9 schools remained open in a town of Bihar. Easy to read, easy to digest — because there are only four numbers to keep track of.
Indian population had risen to 102 crore, of whom 49 crore were female and 53 crore male. Around 74 crore people lived in rural India and 28 crore in towns and cities. Of the 102 crore, 40 crore were workers and 62 crore were non-workers. The urban share showed even more non-workers (19 crore) against workers (9 crore), while the rural population had 31 crore workers out of 74 crore. Try answering "how many rural female workers were there?" from this paragraph alone — your eyes have to dart back and forth.
✓ Strengths of textual presentation
- Simple — needs no special skill from the writer.
- Allows the writer to emphasise particular figures using bold, italics or surrounding commentary.
- Works well for very small datasets like Case 1.
✗ Weaknesses of textual presentation
- The reader must read the entire paragraph just to find one number.
- Comparisons across categories are hard — the eye cannot scan rows and columns.
- Becomes unmanageable as soon as the dataset grows beyond a handful of figures.
4.3 Tabular Presentation of Data
In tabular presentation?, data are placed in rows (read horizontally) and columns (read vertically). The intersection of a row and a column is called a cell, and each cell holds one piece of information that links a row attribute with a column attribute. Tabulation organises data for further statistical treatment and decision-making.
4.3.1 NCERT's Worked Example — Literacy in India by Sex and Location
Table 4.1 in NCERT records literacy rates (per cent of population aged 7 years and above) from Census 2011, classified by sex (male, female, total) and location (rural, urban, total). It is a 3 × 3 table — three rows, three columns — giving nine cells of information.
| Sex | Rural | Urban | Total |
|---|---|---|---|
| Male | 79 | 90 | 82 |
| Female | 59 | 80 | 65 |
| Total | 68 | 84 | 74 |
Source: Census of India 2011. Literacy rates relate to population aged 7 years and above.
Notice how a single row instantly answers "what is the female literacy rate in urban India?" — 80%. The same question, put to NCERT's textual paragraph (Case 2), would force the reader to scan the whole page. That is the core advantage of tabulation.
4.3.2 The Four Bases of Classification Inside a Table
Inside any tabular presentation, the data must be classified by some logic. NCERT identifies four kinds of classification.
4.3.3 Quantitative Classification — Bihar Election Survey (Table 4.2)
NCERT's Table 4.2 distributes 542 respondents in an election study by age in years. Quantitative classes (20–30, 30–40, …) are formed by assigning class limits. The table also lists the percentage share — and asks you to fill in the missing figures. Below is the completed reconstruction.
| Age group (years) | No. of respondents | Per cent |
|---|---|---|
| 20–30 | 3 | 0.55 |
| 30–40 | 61 | 11.25 |
| 40–50 | 132 | 24.35 |
| 50–60 | 153 | 28.24 |
| 60–70 | 140 | 25.83 |
| 70–80 | 51 | 9.41 |
| 80–90 | 2 | 0.37 |
| All | 542 | 100.00 |
Source: Assembly election Patna Central constituency 2005, A.N. Sinha Institute of Social Studies, Patna. Classifying characteristic = age in years.
4.3.4 Temporal Classification — Yearly Sales of a Tea Shop (Table 4.3)
When the classifying variable is time itself, the table is a temporal classification. NCERT's Table 4.3 records the yearly sales (Rs in lakhs) of a tea shop from 1995 to 2000.
| Year | Sale (Rs in lakhs) |
|---|---|
| 1995 | 79.2 |
| 1996 | 81.3 |
| 1997 | 82.4 |
| 1998 | 80.5 |
| 1999 | 100.2 |
| 2000 | 91.2 |
Data Source: Unpublished data.
4.3.5 Spatial Classification — India's Exports by Destination (Table 4.4)
When the classifying variable is geographical place, the table is a spatial classification. NCERT's Table 4.4 shows the share of total Indian exports going to different destinations in 2013–14, with the world total at US $314.40 billion.
| Destination | Export Share (%) |
|---|---|
| USA | 12.5 |
| Germany | 2.4 |
| Other EU | 10.9 |
| UK | 3.1 |
| Japan | 2.2 |
| Russia | 0.7 |
| China | 4.7 |
| West Asia – Gulf Coop. Council | 15.3 |
| Other Asia | 29.4 |
| Others | 18.8 |
| All | 100.0 |
Total Exports: US $314.40 billion. Source: Reproduced from NCERT, classified by destination country/region.
Rewrite the six rows of Table 4.3 as a single textual paragraph (without using any table or list). Then ask a friend to find the year of highest sales just by reading your paragraph aloud. Note how long it takes.
4.4 Tabulation of Data and the Eight Parts of a Statistical Table
To construct a useful table you must know its standard parts. NCERT lists eight elements that together make a good statistical table. Tabulation can be one-way, two-way or three-way depending on the number of characteristics involved.
4.4.1 Worked Reconstruction — Table 4.5 (Workers and Non-workers, 2001)
Table 4.5 is NCERT's full-anatomy worked example. It restates the same data that Case 2 presented in running text — but now arranged as a three-way classification by location (rural/urban/all), gender (male/female/total), and worker status (main worker, marginal worker, total worker, non-worker, total). The unit is crore, and figures are rounded.
| Location | Gender | Main Worker | Marginal Worker | Total Workers | Non-worker | Total |
|---|---|---|---|---|---|---|
| Rural | Male | 17 | 3 | 20 | 18 | 38 |
| Female | 6 | 5 | 11 | 25 | 36 | |
| Total | 23 | 8 | 31 | 43 | 74 | |
| Urban | Male | 7 | 1 | 8 | 7 | 15 |
| Female | 1 | 0 | 1 | 12 | 13 | |
| Total | 8 | 1 | 9 | 19 | 28 | |
| All | Male | 24 | 4 | 28 | 25 | 53 |
| Female | 7 | 5 | 12 | 37 | 49 | |
| Total | 31 | 9 | 40 | 62 | 102 |
Source: Census of India 2001. Note: Figures rounded to the nearest crore. (Table 4.5 presents the same data NCERT first showed as Case 2 in textual form.)
4.5 Designing a Good Table — Practical Rules
NCERT lists three short activities about table design. Pulled together they form a useful checklist for any researcher.
- Two rows and two columns minimum. A table cannot have just one row or one column — it would no longer be a "table" but a list. So at least two rows and two columns are required to form a real table.
- Captions and stubs may be quantitative. Both row and column headings can be quantitative (Table 4.2's age groups appear as stubs; class intervals can also appear as captions). They are not restricted to qualitative attributes.
- Round large figures, state the rounding method. If the body shows millions or crores, round to a sensible number of digits and tell the reader (e.g. "rounded to the nearest crore").
- State all units along with the title. If different parts of the table use different units (e.g. one column in rupees, another in tonnes), state each unit alongside its caption or stub.
- Add source and footnotes. The data are not yours unless you collected them — a source note is mandatory. A footnote handles any quirk that the body cannot explain by itself.
NCERT asks you to present Table 4.2 (age and respondents) and Table 4.3 (yearly tea-shop sales) after appropriate rounding. Pick a sensible rule and apply it to every figure.
Table 4.3 (rounded to the nearest Rs lakh): 79, 81, 82, 81, 100, 91. The trend is preserved while the eye no longer has to read decimals.
NCERT's activity asks you to present the first two sentences of Case 2 (population, female/male, rural/urban) as a table. Some details are scattered later in the chapter. Draft the table.
| Location | Male | Female | Total |
|---|---|---|---|
| Rural | 38 | 36 | 74 |
| Urban | 15 | 13 | 28 |
| All | 53 | 49 | 102 |
NCERT's Activity in §4.3 asks you to construct a table presenting your classmates' preference for Star News, Zee News, BBC World, CNN, Aaj Tak and DD News. Sketch the table on paper and identify all eight parts (number, title, captions, stubs, body, unit, source, note).
| Channel | Boys | Girls | Total |
|---|---|---|---|
| Star News | 5 | 4 | 9 |
| Zee News | 4 | 6 | 10 |
| BBC World | 2 | 1 | 3 |
| CNN | 1 | 2 | 3 |
| Aaj Tak | 6 | 3 | 9 |
| DD News | 2 | 4 | 6 |
| All | 20 | 20 | 40 |

Frequently Asked Questions — Presentation of Data — Textual and Tabular Methods
What are the main parts of a statistical table in NCERT Class 11 Statistics Chapter 4?
A statistical table has seven essential parts according to NCERT Class 11 Statistics Chapter 4: table number, title (descriptive heading), head-note (units of measurement in brackets), captions (column headings, including main and sub-captions), stub (row headings on the left), body (the actual data cells), source note (where the data comes from), and footnote (clarifications on specific entries). Each part has a fixed position and purpose. A well-constructed table is self-explanatory — a reader should be able to interpret it without reading the surrounding text.
What is the difference between textual and tabular presentation of data?
Textual presentation describes data within paragraphs of prose, weaving numbers into sentences for context — useful when there are very few numbers or when the discussion is qualitative. Tabular presentation arranges data in rows and columns with clear captions, stubs and a defined body — making it easier to read, compare and analyse large datasets. NCERT Class 11 Statistics Chapter 4 Part 1 prefers tabular presentation for any non-trivial dataset because it saves space, shows totals and comparisons clearly, and is the foundation for further statistical or graphical analysis. Textual is best for emphasis on a single key figure.
What is a head-note in a statistical table and where is it placed?
A head-note in a statistical table is a short statement, usually placed in brackets just below the title, that gives the unit of measurement or any general qualification applying to the entire table — for example '(in tonnes)', '(₹ in crores)' or '(figures rounded to nearest hundred)'. NCERT Class 11 Statistics Chapter 4 Part 1 explains that the head-note prevents repetition of units in every cell and avoids confusion when a reader interprets the data. If different parts of the table use different units, those units are placed inside individual captions or as footnotes instead.
How do you classify statistical tables in NCERT Class 11?
NCERT Class 11 Statistics Chapter 4 Part 1 classifies tables on three bases. By purpose: general-purpose (reference) tables that present data without focus, versus special-purpose (summary) tables that highlight a specific finding. By originality: original tables containing primary data versus derivative tables based on secondary computations. By construction: simple tables presenting one characteristic, double tables with two characteristics, three-way tables with three characteristics, and complex (manifold) tables with many characteristics shown together. The choice of classification depends on the depth of analysis needed for the dataset.
What is a stub in a statistical table in NCERT Class 11 Statistics?
The stub of a statistical table is the column on the extreme left that contains the row headings, identifying what each row represents. NCERT Class 11 Statistics Chapter 4 Part 1 explains that the stub is to rows what the caption is to columns. A good stub uses short, clear labels, arranges entries in a logical order (alphabetical, chronological, or magnitude), and may include sub-stubs for further breakdown. Together with the captions at the top, the stub on the left frames the body of the table so that any cell can be uniquely identified by its row-and-column reference.
Why is a source note important in a statistical table?
A source note placed below a statistical table identifies the original source of the data — for example NSSO Round 75, RBI Annual Report 2023, or Census of India 2011 — and is essential for credibility, traceability and academic honesty. NCERT Class 11 Statistics Chapter 4 Part 1 stresses that secondary data without a source citation is unverifiable and unusable for serious analysis. The source note also lets readers find more detail, check definitions, and assess whether the data is fit for their own purpose. A footnote may follow to clarify specific cells, revisions or methodology changes.
