Question

data may be classified by one of the four levels of measurement. what is the name of the lowest level?

nominal

ordinal

ratio

interval

simple

Explanation:

The four levels of measurement (from lowest to highest) are nominal, ordinal, interval, and ratio. The nominal level is the lowest as it only involves categorizing data with no order or numerical value beyond identification (e.g., gender, eye color categories). Ordinal has order but no consistent interval, interval has order and consistent interval but no true zero, and ratio has all including a true zero. "Simple" is not a standard level of measurement.

Answer:

A. nominal
