If a pediatrician wants to determine the relation that may exist between a ?child's height and head circumference, she he randomly selects 8? children, measures their height and head? circumference, and obtains the data shown below. So how would I compute the linear correlation coefficient between the height and head circumference of a child?
n n Height (Inches) Head Circumference (Inches)
