DA0-002 Data Concepts and Environments Practice Question
Which THREE of the following are properties of ratio data? (Choose THREE.)
⚠ Common exam trap
Candidates often confuse the 'meaningful zero' property with the ability to have negative values, or they think categorization is a defining feature of ratio data, when it is actually a property shared by all measurement scales.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Supports multiplication and division
Ratio data supports multiplication and division because it has a true, meaningful zero point that indicates the absence of the measured attribute. This allows ratios to be computed (e.g., one value is twice another), which is a defining property of ratio scales in measurement theory.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data can be categorized into groups
Why it's wrong here
Categorization is a property of nominal/ordinal data, not specific to ratio.
- ✗
Allows negative values
Why it's wrong here
True zero implies no negative values (e.g., weight cannot be negative).
- ✓
Supports multiplication and division
Why this is correct
Ratio data allows meaningful ratios (e.g., twice as heavy).
- ✓
Intervals between values are equal
Why this is correct
Equal intervals allow arithmetic operations.
- ✓
Has a meaningful zero point
Why this is correct
A true zero indicates absence of the attribute.
