Details
The midparent's height is an average of the fathers height and 1.08 times
the mother's. In the data there are 205 different parents and 928 children.
The data here is truncated at the ends for both parents and
children so that it can be treated as numeric data. The data were
tabulated and consequently made discrete. The father.son data set is
similar data used by Galton and is continuous.
