On this Picostat.com statistics page, you will find information about the ducks data set which pertains to Behavioral and Plumage Characteristics of Hybrid Ducks. The ducks data set is found in the boot R package. You can load the ducks data set in R by issuing the following command at the console data("ducks"). This will load the data into a variable called ducks. If R says the ducks data set is not found, you can try installing the package by issuing this command install.packages("boot") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the ducks R data set. The size of this file is about 77 bytes.

Behavioral and Plumage Characteristics of Hybrid Ducks

Description

The ducks data frame has 11 rows and 2 columns.

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.
