Question

1. at our high school, we are required to keep the following information on file for each student: age, race, days absent, current grade level, standardized test scores, and if the student has a 504 or iep. 3) mcdonald’s has information on their food items posted on their website. they list the type of meat used in the item, the number of calories, the approximate weight of the item, and if the item is on the breakfast menu or the regular menu. example: a hospital keeps track of prenatal statistics on the newborns born in their hospital. for variables below, identify each as categorical, continuous, or discrete. 4) the mother’s age 5) the number of weeks the pregnancy lasted 6) the birth weight of the baby 7) the baby’s apgar score (a scale of 0 - 10) 8) the sex of the baby 9) the type of birth (cesarean, natural, induced) 10) the level of prenatal care the mother had (high, normal, none)

Explanation:

Step1: Recall variable - type definitions

Categorical variables are non - numeric and represent groups or categories. Discrete variables are numeric and can only take on certain values (usually whole numbers). Continuous variables are numeric and can take on any value within a range.

Step2: Analyze mother's age

Mother's age can take on any value within a reasonable range (e.g., 15 - 50 years) and can be measured with decimal precision in theory (e.g., 25.5 years), so it is a continuous variable.

Step3: Analyze number of weeks of pregnancy

The number of weeks of pregnancy is a whole - number value (e.g., 38 weeks, 40 weeks), so it is a discrete variable.

Step4: Analyze birth weight of the baby

Birth weight can take on any value within a range (e.g., 2.5 kg, 3.25 kg) and can be measured with decimal precision, so it is a continuous variable.

Step5: Analyze baby's APGAR score

The APGAR score is a whole number between 0 and 10 (e.g., 7, 8), so it is a discrete variable.

Step6: Analyze sex of the baby

The sex of the baby is either male or female, which are categories, so it is a categorical variable.

Step7: Analyze type of birth

The type of birth (cesarean, natural, induced) are categories, so it is a categorical variable.

Step8: Analyze level of prenatal care

The level of prenatal care (high, normal, none) are categories, so it is a categorical variable.
