This shows two box and whisker plots side by side.

Each box and whisker plot consists of a vertical plot. There is a central rectangle, with a horizontal line drawn across near the centre. Above and below the rectangle a vertical line extends terminating in a short horizontal line. For each plot, the upper vertical line is much longer than the lower. For the left hand plot the central horizontal line is near the bottom of the rectangle, for the right hand plot the central horizontal line is near the centre of the rectangle.

The vertical axis is labeled "count" and has a scale marked 0, 20000, 40000, 60000, 80000, 100000. The horizontal axis is labeled to indicate two groups: "Urothelial cancers" and "Normal bladder".

Each element in the left plot is much higher than the corresponding element on the right.

Back to question on a comparison of two small groups.
