With data obtained from a national database on childbirth, Matulavich et al. (A-16) examined the number of courses of prescribed steroids a mother took during pregnancy (STEROIDS). The size of the baby was measured by length (cm), weight (grams), and head circumference (cm). Calculate the correlation of the number of courses of steroids with each of the three outcome variables.
