A graph where the horizontal axis is labeled "Stress (100mm VAS)" and numbered 0, 20, 40, 60, 80, 100 and the vertical axis is labeled "Frequency" and numbered 0, 10, 20, 30, 40.
There are vertical bars with bases and heights as follows: 10 to 20, 1, 20 to 30, 4, 30 to 40, 19, 40 to 50, 32, 50 to 60, 18, 60 to 70, 34, 70 to 80, 38, 80 to 90, 36 and 90 to 100, 18.
The words "Mean minus 2 S D" appear below the graph with a line pointing upwards to stress = 26.6 milimetres. The words "Mean minus S D" appear below the graph with a line pointing upwards to stress = 45.7 milimetres. The word "Mean" appear below the graph with a line pointing upwards to stress = 64.8 milimetres. The words "Mean plus S D" appear below the graph with a line pointing upwards to stress = 83.9 milimetres. The words "Mean plus 2 S D" appear below the graph with a line pointing upwards to stress = 103 milimetres.
