and lowest, in one case for those in the least crowded condition, and 

 in the other case for those in the most crowded condition. This would 

 give a slight indication that yield increases in its correlation with height 

 as crowding increases up to a certain point, beyond which there is a gradual 

 decrease in correlation.
