Project: A Research Project on Birth Weight

The data file provided below is a sample of birth records taken by the North Carolina State Center for Health and Environmental Statistics. The data set represents a sample of around a thousand births taken within the state of North Carolina. Of particular interest will be incidents of Low Infant Birth Weight. Low birth weight has been associated with weaker development of many characteristics such as intelligence, coordination, strength, etc. Low birth weight is commonly defined as less than 2500 grams (approximately 88 ounces).


The variables examined are:


Sex of child (1=Male, 2=Female)


Race of child (0=other Nonwhite, 1=White, 2=Black, 3=American Indian,  4=Chinese, 5=Japanese, 6=Hawaiian, 7=Filipino, 8=Other)

Number of children born of the pregnancy


Weight of child in total ounces


Weight of child (1=Below normal birth weight, 0=Normal birth weight)

Data values are labeled in the SPSS data file provided above.
