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 tail-feather length (measuring the R1 central tail feather) and weight in a sample of 20 male longtailed finches raised in an aviary. The data are represented in the scatterplot below, along with the least-squares regression line equation and R2.
