The table shows information about the height of 40 plants. Draw a histogram to represent the heights.

Height, h cm	Frequency
0 < h ≤ 5	6
5 < h ≤ 15	15
15 < h ≤ 25	9
25 < h ≤ 50	10

A histogram is used to represent continuous data, especially when the class intervals (or widths) are unequal. The area of each bar is proportional to the frequency, which means the height of each bar must be the **Frequency Density**. The formula is: **Frequency Density = Frequency / Class Width** Let's calculate this for each group: * **Group 1: 0 < h ≤ 5** * Frequency = 6 * Class Width = 5 - 0 = 5 * Frequency Density = 6 / 5 = **1.2** * **Group 2: 5 < h ≤ 15** * Frequency = 15 * Class Width = 15 - 5 = 10 * Frequency Density = 15 / 10 = **1.5** * **Group 3: 15 < h ≤ 25** * Frequency = 9 * Class Width = 25 - 15 = 10 * Frequency Density = 9 / 10 = **0.9** * **Group 4: 25 < h ≤ 50** * Frequency = 10 * Class Width = 50 - 25 = 25 * Frequency Density = 10 / 25 = **0.4** Now, we draw the histogram: - The first bar goes from 0 to 5 on the x-axis and has a height of 1.2 on the y-axis. - The second bar goes from 5 to 15 and has a height of 1.5. - The third bar goes from 15 to 25 and has a height of 0.9. - The fourth bar goes from 25 to 50 and has a height of 0.4.
