NCERT Solutions for Class 4th Maths Chapter 14 Data Handling
Updated on 2026-09-19
About this chapter
Information that we collect and count is called data. A good survey question has only one answer, so each child gives exactly one vote. While collecting, write each answer down as it comes — a short letter like M, L or A is quick to write. A table puts like with like. It has one row for each choice and one number beside it. A table is easier to read than a raw list, because the counting is already done. In a pictograph one picture stands for one thing, so a longer row always means a bigger number. Different ways of recording hold different information. Pictures of children keep boys and girls apart; pictures of golas only give the total. The counts in a table must add up to the number of people you asked. That is how you check your work.

Quick revision
| Idea | What it means | Example from the chapter | Remember this |
|---|---|---|---|
| Data | Information we collect and count | The 45 answers on the clipboard | Collect first, count later |
| Good question | A question with only one answer | “Which subject do you like the most?” | One child, one vote |
| Poor question | A question with many answers | “Which subjects do you like?” | Cannot be counted fairly |
| Recording | Writing each answer as it comes | M, L, T, A, P.E. on the clipboard | Use a short letter |
| Table | Rows of choices with counts beside them | Mathematics 10, Languages 8, … | Like with like |
| Most common | The choice with the biggest count | Physical Education, 11 children | Look for the largest number |
| Least common | The choice with the smallest count | The World Around Us, 7 children | Look for the smallest number |
| Check the total | All counts added = people asked | 10 + 8 + 7 + 11 + 9 = 45 | If not, count again |
| Pictograph | A picture drawn for each thing counted | One sandwich picture = one sandwich | Longer row = bigger number |
| Reading a pictograph | Count the pictures in the row | Day 3 sandwiches: 9 + 9 = 18 | Count both lines of a row |
| Tie | Two or more choices with the same top count | Girls ate 4 red, 4 orange, 4 yellow golas | There can be more than one winner |
| Two records, one event | The same data shown in two ways | Rohan drew children, Anjali drew golas | Both give the total 30 |
