Golf tee data

Description

The data are from independent surveys by eight observers of a population of 250 groups (760 individuals) of golf tees. The tees, of two colours, were placed in groups of between 1 and 8 in a survey region of 1680 m^2, either exposed above the surrounding grass, or at least partially hidden by it. They were surveyed by the 1999 statistics honours class at the University of St Andrews.

Format

Data is a list with 4 elements each of which is a data.frame:

Details

We treat each group of golf tees as a single animal with size equal to the number of tees in the group; yellow tees are male, green are female; tees exposed above the surrounding grass are classified as exposed, others as unexposed. We are grateful to Miguel Bernal for making these data available; they were collected by him as part of a masters project.
