Question

determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. ages (years) of children, such as 5, 6, 7, 8, and 9 choose the correct answer below. nominal interval ratio ordinal

Explanation:

The ratio level of measurement has a true zero point. Age has a true zero (birth represents the start, i.e., age 0), and ratios between values are meaningful (a 6 - year - old is twice as old as a 3 - year - old). Nominal is for naming (e.g., gender), ordinal has order but no equal intervals (e.g., rankings), and interval has equal intervals but no true zero (e.g., Celsius temperature).

C. Ratio
