Question

researchers investigating the impact of prenatal care on newborn health collected data from 866 births during 1997 - 1999. they kept track of the mothers age, the number of weeks the pregnancy lasted, the type of birth (cesarean, induced, natural), the level of prenatal care the mother had (none, minimal, adequate), the weight and sex of the infant, and whether the infant exhibited health problems (none, minor, major). keeping in mind the sample, identify each variable as a categorical variable, a quantitative variable, or not a variable. the weight of the infant the infants health problems the mothers age the duration of the study 1. quantitative variable 2. categorical variable 3. not a variable

Explanation:

The weight of the infant

Infant weight takes numerical values (e.g., 3 kg, 4.5 kg) and can be measured/quantified, so it's a quantitative variable.

Infant health problems are categorized into none, minor, major (distinct groups with no numerical meaning), so it's a categorical variable.

Mother's age is a numerical value (e.g., 25 years, 30 years) that can be measured/quantified, so it's a quantitative variable.

Answer:

1. Quantitative Variable

The infant's health problems
