NDA 1 2025 Maths, question 104
The frequency distribution of height of students of a class is given below:
| Height (in cm) | Number of Students |
|---|---|
| 160–162 | 12 |
| 162–164 | 15 |
| 164–166 | 24 |
| 166–168 | 13 |
Solution.
Answer: (c) histogram
- Height is a continuous variable grouped into adjacent class intervals.
- A histogram places these intervals along the horizontal axis with adjoining bars.
- All class widths are 2 cm, so bar heights can be proportional directly to the frequencies.
