Draw histograms for the following frequency distributions :

Class interval	Frequency
10 - 16	15
16 - 22	23
22 - 28	30
28 - 34	20
34 - 40	16

Steps of construction of histogram :

1. Since, the scale on x-axis starts at 10, a break (kink) is shown near the origin on x-axis to indicate that the graph is drawn to scale beginning at 10.

2. Take 2 cm along x-axis = 6 units.

3. Take 1 cm along y-axis = 5 units.

4. Construct rectangles corresponding to the above continuous frequency distribution table.

The required histogram is shown in the below figure:
