Collected data సాధారణంగా పెద్ద మొత్తంలో మరియు unorganised formలో ఉంటుంది. అటువంటి dataను అర్థం చేసుకోవడానికి ముందుగా Classification చేసి, తర్వాత rows మరియు columnsలో systematicగా present చేస్తారు. ఈ ప్రక్రియను Tabulation అంటారు.

Classified or grouped dataను table రూపంలో summarize చేయడం వల్ల informationను సులభంగా అర్థం చేసుకోవచ్చు మరియు required informationను త్వరగా locate చేయవచ్చు.
TABULATION
= Systematic presentation of classified data in Rows and Columns
Statistical Table అనేది classified dataను rows మరియు columnsలో systematically arrange చేసిన presentation.
| Year | Production (Tonnes) |
|---|---|
| 2022 | 500 |
| 2023 | 620 |
| 2024 | 700 |
| 2025 | 760 |
Here:
Columns → Vertical arrangements
Cells → Boxes formed by the intersection of rows and columns
Classification మరియు Tabulation closely related processes. Dataను tableలో present చేయడానికి ముందు దానిని suitable groups/classesగా classify చేయాలి.
Classification is the first step in Tabulation.
| Classification | Tabulation |
|---|---|
| Data are divided into groups/classes | Classified data are arranged in rows and columns |
| Groups similar items together | Presents grouped information systematically |
| Precedes tabulation | Generally follows classification |
| Helps organise raw data | Helps comparison, analysis and presentation |
Uploaded statistical material lists the following major objectives:
Investigationలో required factsను systematically study చేయడానికి సహాయపడుతుంది.
2. To facilitate comparison
Different groups, periods or categories మధ్య comparison సులభమవుతుంది.
3. To locate omissions and errors
Dataలో missing information లేదా errors గుర్తించడం సులభం.
4. To use space economically
Large informationను comparatively small spaceలో present చేయవచ్చు.
5. To study trends
Time లేదా categoriesలో changes/trendsను observe చేయవచ్చు.
6. To simplify data
Complex dataను understandable formలోకి మార్చుతుంది.
7. Future reference
Tabulated informationను future reference కోసం ఉపయోగించవచ్చు.
Tabulation → Simplify + Compare + Analyse + Detect Errors + Save Space + Study Trend + Reference
Large and complex data become easier to understand.
Facilitates Comparison:
Related facts can be compared easily.
Helps Statistical Computation:
Averages, dispersion, correlation and other statistical measures can be calculated conveniently.
Saves Space:
Facts are presented in minimum possible space and unnecessary repetition is avoided.
Easy Reference:
Required information can be located quickly.
Basis for Diagrams and Graphs:
Tabulated data can be conveniently used for diagrammatic and graphical presentation.
Tabulation dataను merely attractiveగా చూపడం మాత్రమే కాదు. Further statistical treatment మరియు decision-makingకు organised baseను అందిస్తుంది.
Tabulation organises data for
→ Further Statistical Treatment
→ Comparison
→ Decision-making
A good statistical tableలో informationను correctly interpret చేయడానికి several essential parts ఉంటాయి.
Every tableకు identification కోసం number assign చేస్తారు. ఒక report/bookలో multiple tables ఉన్నప్పుడు ఒక tableను మరొక table నుండి distinguish చేయడానికి Table Number ఉపయోగపడుతుంది.
Table 1
Table 2
Table 3
or
Table 2.1
Table 2.2
Table 4.5
Table 4.5 సాధారణంగా fourth chapterలో fifth tableను indicate చేయవచ్చు.
Tableలో ఏమి information ఉందో తెలియజేసే headingను Title అంటారు.
A good title should be:
Brief
Carefully worded
Free from ambiguity
Title → contents of entire table
Caption → contents of a column
Each columnపై ఇచ్చే designation లేదా headingను Caption లేదా Column Heading అంటారు.
| Year | Production | Exports |
|---|---|---|
| 2024 | 500 | 120 |
Year → Caption
Production → Caption
Exports → Caption
Each rowకు ఇచ్చే heading/designationను Stub లేదా Row Heading అంటారు.
| Category | Number |
|---|---|
| Male | 520 |
| Female | 480 |
Male మరియు Female ఇక్కడ row designations/stub items.
CAPTION → COLUMN
STUB → ROW
Tableలో actual numerical information ఉండే main portionను Body of the Table అంటారు.
Each numerical value యొక్క location corresponding row మరియు column ద్వారా determine అవుతుంది.
Tableలో figures ఏ unitsలో measure చేశారో clearly state చేయాలి.
Population → (in lakh)
Income → (₹ crore)
Production → (tonnes)
Literacy Rate → (per cent)
Entire tableకు same unit ఉంటే titleతో unitను state చేయవచ్చు. Different rows/columnsకు different units ఉంటే respective stubs/captionsతో units ఇవ్వాలి.
Tableలోని data ఎక్కడి నుండి obtained అయ్యిందో indicate చేసే statementను Source అంటారు.
Source: Census of India
Source సాధారణంగా table యొక్క bottomలో ఇవ్వబడుతుంది.
Where did the data come from?
Tableలోని dataకు సంబంధించిన special feature లేదా clarificationను explain చేయడానికి Note ఉపయోగిస్తారు.
Note: Figures are rounded to the nearest crore.
Source → Where data came from

Students of a College by Gender, 2026
(Unit: Number)
| Gender | First Year | Second Year | Total |
|---|---|---|---|
| Male | 120 | 130 | 250 |
| Female | 140 | 160 | 300 |
| Total | 260 | 290 | 550 |
Title → Students of a College by Gender, 2026
Unit → Number
Captions → First Year, Second Year, Total
Stubs → Male, Female, Total
Body → 120, 130, 250, 140, 160, 300...
Number of characteristics used ఆధారంగా tablesను mainly:
2. Two-Way Table
3. Manifold Table
Dataను one characteristic ఆధారంగా classify చేసి present చేస్తే Simple or One-Way Table అంటారు.
| Gender | Number of Students |
|---|---|
| Male | 250 |
| Female | 300 |
| Total | 550 |
Therefore → One-Way Table
Dataను two characteristics ఆధారంగా classify చేస్తే Two-Way Table అంటారు.
| Gender | Rural | Urban | Total |
|---|---|---|---|
| Male | 180 | 120 | 300 |
| Female | 200 | 150 | 350 |
1. Gender
2. Location
Therefore → Two-Way Table
Dataను more than two characteristics ఆధారంగా classify చేస్తే Manifold Table అంటారు.
Gender
+ Location
+ Employment Status
→ Manifold Classification / Table
1 Characteristic → One-Way
2 Characteristics → Two-Way
More than 2 → Manifold
Tabulationలో dataను nature of characteristic ఆధారంగా four important waysలో classify చేయవచ్చు:
| Classification | Basis | Example |
|---|---|---|
| Qualitative | Attributes / qualities | Sex, nationality, occupation |
| Quantitative | Numerical magnitude | Age, income, height, weight |
| Temporal / Chronological | Time | Production by year |
| Spatial / Geographical | Place / location | Population by State |
Non-measurable characteristics or attributes ఆధారంగా dataను classify చేస్తే Qualitative Classification.
Sex
Nationality
Occupation
Marital Status
Social Status
Numerically measurable characteristics ఆధారంగా classification చేస్తే Quantitative Classification.
Age
Height
Weight
Income
Expenditure
Price
Production
Dataను time ఆధారంగా arrange/classify చేస్తే Chronological Classification అంటారు.
| Year | Production |
|---|---|
| 2022 | 400 |
| 2023 | 450 |
| 2024 | 520 |
| 2025 | 600 |
Dataను places, regions, states, countries etc. ఆధారంగా classify చేస్తే Geographical or Spatial Classification.
| State | Production |
|---|---|
| Andhra Pradesh | 650 |
| Telangana | 500 |
| Tamil Nadu | 580 |
| Karnataka | 610 |
Tableలో rows మరియు columns intersection ద్వారా Cells ఏర్పడతాయి.
Cells = 4 × 5
R × C Table → R × C cells
A) 7
B) 12
C) 16
D) 24
