Since the 'whiskers' are just the single min and max, I would put a lot more weight on the box when making observations. 1 2 2 2 2 4 4 5 5 3 3 3 3 10 is fairly symmetric data, but the right whisker would be way out there. That said. The box is a bit skewed to the left too. Not a ton, but it's noticable.
