Both distributions have long left tails (that is, they are negatively skewed), and one rower is much shorter than everyone else (an outlier---maybe she is a cox?)

Basketball has interquartile range 15.3, whiie rowing has IQR 4.35; also, the standard deviation for basketball is larger than that for rowing; these both support the statement that the heights of the basketball players are more spread than those of the rowers. Both distributions have median > mean and Q2 — Q1 > Q3 ~ Q2, which is another indication of negative skewness. : [email protected] , iws‘RQQr’mggfiaXfl Km‘fiakx ism“ We. e331.ng gm.
