David F. Adiele, Uche O. Elem

Abstract


This paper examined the relationship between birth weight and head circumference of babies. The ordinary least square method of linear regression analysis and Chi-square test were utilized to achieve its objectives. The hypothesis that birth weight is independent of head circumference; birth weight is independent of sex; and head circumference is independent of sex was rejected at 5 percent level of significance. The result showed that birth weight is dependent on head circumference and sex; and that head circumference depends on sex. Birth weight and head circumference of male babies are higher than that of the female babies. However, female have normal head circumference than male. Moreso, a significant linear positive relationship exists between birth weight and head circumference.
