DA0-001 Comparing and Contrasting Data Concepts Practice Question
This DA0-001 practice question tests your understanding of comparing and contrasting data concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO data types are considered quantitative? (Select two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Customer satisfaction rating (1-5)
Customer satisfaction rating (1-5) is quantitative because it represents numerical values that can be measured and subjected to mathematical operations, such as calculating an average. Temperature in Celsius is also quantitative as it is a continuous numerical measurement on an interval scale, allowing for meaningful arithmetic comparisons. Both options involve numeric data that can be analyzed statistically.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Customer satisfaction rating (1-5)
Why this is correct
Correct. Although ordinal, it is a numeric rating and considered quantitative.

✓
Temperature in Celsius
Why this is correct
Correct. Temperature is measured on a continuous quantitative scale.

✗
Product color
Why it's wrong here
Incorrect. Product color is a categorical (qualitative) variable.
✗
Zip code
Why it's wrong here
Incorrect. Zip code is a nominal identifier, not quantitative.
✗
Employee ID
Why it's wrong here
Incorrect. Employee ID is a nominal identifier, not quantitative.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often mistake numeric-looking identifiers (like zip codes or employee IDs) for quantitative data, failing to recognize that they are nominal categorical variables with no mathematical significance.
Detailed technical explanation
How to think about this question
Quantitative data is classified as either discrete (e.g., counts like 1-5 ratings) or continuous (e.g., temperature). In data analysis, distinguishing between interval and ratio scales is critical: temperature in Celsius is interval (no true zero), while a rating scale is often treated as ordinal but can be analyzed as discrete quantitative if intervals are assumed equal. Real-world scenarios, such as calculating mean customer satisfaction or average daily temperature, rely on this distinction to apply appropriate statistical tests.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the DA0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
