QQuestion
Using graph paper, draw a histogram for the following distribution of marks obtained by 164 students and hence find the mode. Take 2 cm = 10 marks on one axis and 2 cm = 10 students on the other.
| Marks | Number of students |
|---|---|
| 30–40 | 10 |
| 40–50 | 26 |
| 50–60 | 40 |
| 60–70 | 54 |
| 70–80 | 34 |
✓Answer
From graph,
The Mode = L = 64 marks (approx.)
Hence, mode = 64.
