| Galton | R Documentation |
In the 1880's, Francis Galton was developing ways to quantify the heritability of traits. As part of this work, he collected data on the heights of adult children and their parents.
data(Galton)
A data frame with 898 observations on the following variables.
family a factor with levels for each family
father the father's height (in inches)
mother the mother's height (in inches)
sex the child's sex: F or M
height the child's height as an adult (in inches)
nkids the number of adult children in the family, or, at least,
the number whose heights Galton recorded.
Entries were deleted for those children whose heights were not recorded numerically by Galton, who sometimes used entries such as "tall", "short", "idiotic", "deformed" and so on.
The data were transcribed by J.A. Hanley who has published them at http://www.medicine.mcgill.ca/epidemiology/hanley/galton/
