The linked page has box and whisker plots. On a box and whisker plot the lower bar is the min, the upper bar is the max. The box goes from 25th percentile to 75th percentile while the bar in the middle of the box is the 50th percentile.
Therefore the stats you mentioned are all there min, max, and average with two different definitions of average given (geometric mean, and 50th percentile).
It would be nice to be able to see the numbers in a table (perhaps in a auxiliary page, instead of the main page). Sometimes people want to rearrange the data or use another representation. (log scale? sort by 75% quartile? ...)
