Golf tee data


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.


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


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.
