Question

multiple choice question
what level of data is represented by the ages of patients in a local hospital?
ordinal
nominal
interval
ratio

Explanation:

Ratio data has a true zero point, allows meaningful comparisons of magnitudes, and supports all arithmetic operations. Patient age has a true zero (birth, age 0), and differences/ratios (e.g., a 40-year-old is twice as old as a 20-year-old) are meaningful. Ordinal data ranks without consistent intervals, nominal data labels categories, and interval data lacks a true zero.

Answer:

Ratio
