描述----------Description----------
The ducks data frame has 11 rows and 2 columns.
ducks数据框有11行2列。
Each row of the data frame represents a male duck who is a second generation cross of mallard and pintail ducks. For 11 such ducks a behavioural and plumage index were calculated. These were measured on scales devised for this experiment which was to examine whether there was any link between which species the ducks resembled physically and which they resembled in behaviour. The scale for the physical appearance ranged from 0 (identical in appearance to a mallard) to 20 (identical to a pintail). The behavioural traits of the ducks were on a scale from 0 to 15 with lower numbers indicating closer to mallard-like in behaviour.
数据框的每一行代表男性谁是第二代交叉的绿头鸭，针尾鸭鸭的鸭。对于一个行为和羽毛指数等11个鸭进行了计算。这些测量，设计规模为这个实验是检查是否有任何一个环节之间的物种鸭相似，身体和他们的行为相似。外表的规模，范围从0（到绿头鸭在外观相同），20（相同的一针尾鸭）。鸭子的行为特征上具有较低的数字表明接近野鸭，像行为规模从0到15。
