A graph where the horizontal axis is labeled "Height (cm)" and numbered 140, 150, 160, 170, 180, 190 and the vertical axis is labeled "Frequency" and numbered 0, 10, 20, 30, 40.
There are vertical bars with bases and heights as follows: 145 to 150, 4, 150 to 155, 2, 155 to 160, 12, 160 to 165, 34, 165 to 170, 27, 170 to 175, 15, 175 to 180, 2, and 180 to 185, 5.
The words "first quartile" appear below the graph, with a line pointing upwards to 160 centimetres. The word "median" appears below the graph, with a line pointing upwards to 163.2 centimetres. The words "third quartile" appear below the graph, with a line pointing upwards to 167.6 centimetres.
