Answer: (A)

Verified step by step guidance

1. Understand that the question asks for the four levels of measurement used to classify data in statistics.
2. Recall that the four levels of measurement are Nominal, Ordinal, Interval, and Ratio, which describe different ways data can be categorized or measured.
3. Nominal level classifies data into distinct categories without any order (e.g., colors, names).
4. Ordinal level classifies data into categories with a meaningful order but without consistent differences between categories (e.g., rankings).
5. Interval and Ratio levels both involve numerical data where differences are meaningful; Interval has no true zero point (e.g., temperature in Celsius), while Ratio has a true zero point allowing for meaningful ratios (e.g., weight, height).
