Galton

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.

datasets

Data sets and utilities from Project MOSAIC (mosaic-web.org) used
    to teach mathematics, statistics, computation and modeling.  Funded by the
    NSF, Project MOSAIC is a community of educators working to tie together
    aspects of quantitative work that students in science, technology,
    engineering and mathematics will need in their professional lives, but
    which are usually taught in isolation, if at all.  A few features take
    advantage of the manipulate package when working in RStudio.

Galton function

A data frame with 898 observations on the following variables.
  <ul><li><code>family</code></li></ul> {a factor with levels for each family}
    <item><code>father</code></item> {the father's height (in inches)}
    <item><code>mother</code></item> {the mother's height (in inches)}
    <item><code>sex</code></item> {the child's sex: <code>F</code> or <code>M</code>}
    <item><code>height</code></item> {the child's height as an adult (in inches)}
    <item><code>nkids</code></item> {the number of adult children in the family, or, at least,
the number whose heights Galton recorded.}
