# Colours of Eyes and Hair of People in Caithness

### Description

Data on the cross-classification of people in Caithness, Scotland, by eye and hair colour. The region of the UK is particularly interesting as there is a mixture of people of Nordic, Celtic and Anglo-Saxon origin.

### Usage

1 |

### Format

A 4 by 5 table with rows the eye colours (blue, light, medium, dark) and columns the hair colours (fair, red, medium, dark, black).

### Source

Fisher, R.A. (1940) The precision of discriminant functions.
*Annals of Eugenics (London)* **10**, 422–429.

### References
