In the following table, the investment made by 210 families is shown. Present it in the form of a histogram.
| Investment (Thousand Rupees) | 10–15 | 15–20 | 20–25 | 25–30 | 30–35 |
|---|---|---|---|---|---|
| No. of families | 30 | 50 | 60 | 55 | 15 |
Answer: Histogram with rectangles of heights 30, 50, 60, 55, 15 on the classes 10–15, 15–20, 20–25, 25–30, 30–35
| Investment (Thousand Rupees) | No. of families |
|---|---|
| 10–15 | 30 |
| 15–20 | 50 |
| 20–25 | 60 |
| 25–30 | 55 |
| 30–35 | 15 |
Steps: Take investment (thousand rupees) on the X-axis and no. of families on the Y-axis, with a convenient scale on each. Since the first class does not start at 0, show a kink mark between the origin and the first class. On each class interval draw a rectangle whose height equals its frequency; adjacent rectangles touch each other (no gaps). The tallest rectangle is for the class 20–25 (frequency 60).
