DA0-002 Data Concepts and Environments Practice Question
A data team is building a predictive model. They have data on 'Number of employees' (whole numbers) and 'Revenue' (currency). Which statement correctly compares these data types?
⚠ Common exam trap
Watch out — candidates often confuse the measurement scale (ratio) with the data type (discrete vs. continuous), leading them to pick option C even though the question specifically asks about data type classification.
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
✓
Number of employees is discrete; revenue is continuous
'Number of employees' is a count of distinct entities, making it discrete data (only whole numbers), while 'Revenue' can take any value within a range (including decimals), making it continuous data. Discrete data arises from counting, whereas continuous data arises from measurement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Number of employees is discrete; revenue is continuous
Why this is correct
Employees are counted in whole units (discrete), while revenue can have fractional values (continuous).
- ✗
Both are continuous data
Why it's wrong here
Number of employees is discrete, not continuous.
- ✗
Both are ratio data
Why it's wrong here
Both can be ratio, but the question is about discrete vs continuous.

Number of employees is qualitative; revenue is quantitative
Why it's wrong here
