EMC Proven Professional – Data Science and Big Data Analytics — Question 34

Consider a scale that has five (5) values that range from "not important" to "very important". Which data classification best describes this data?

Answer options

• A. Ordinal
• B. Nominal
• C. Real
• D. Ratio

Correct answer: A

Explanation

The correct answer is 'Ordinal' because the values indicate a clear order of importance. 'Nominal' would apply to categories without any rank, while 'Real' and 'Ratio' pertain to numerical data that have specific mathematical properties, which do not apply in this case.
