Question
Tail-feather length in birds is sometimes a sexually dimorphic trait. That is, the trait differs substantially for males and for females. Researchers studied the relationship between weight, x, and tail-feather length, y, in a sample of five wild male long-tailed finches. The data are given: weight (g) 20.8 19.1 15.9 16.7 15.7 tail length (mm) 82.5 82.5 67.0 70.5 73.5 What are the units of the correlation coefficient for these data? Correlation is a unitless quantity. g/mm units mm units mm/g units
