Weight gradient up the divisions

Every active rikishi (wrestler) has a recorded weight and height. Plotted below: each dot is one wrestler, by division. The progression is steady - Makuuchi (top division) wrestlers average 159kg while Jonokuchi entrants average 127kg. But there are huge bodies at every level and small ones in the top division too. The notched bar shows the median; the shaded band is the middle 50% (interquartile range). For each wrestler's own profile, see the active athletes and the full rikishi directory.
