Question

a 5-star-based review system is best described as which level of measurement?
a. ordinal
b. nominal
c. ratio
d. interval

Explanation:

A 5-star review system has a clear ordered ranking (1 star is worse than 2 stars, etc.), where the order matters but the exact difference between each star level is not a consistent, measurable interval. This matches the definition of ordinal measurement, which focuses on ranked order rather than equal intervals or a true zero point. Nominal measurement only categorizes without order, interval has equal intervals but no true zero, and ratio has both equal intervals and a true zero (none of which apply here).

Answer:

a. Ordinal
