Are the questions aligned with the ASQ CQE Body of Knowledge?

Yes. Each question is written around topics included in the published CQE Body of Knowledge and is tagged to the relevant BoK area. These are original practice questions and are not copied from the actual ASQ exam.

In Review Mode, you receive the correct answer and explanation immediately after answering each question. It is designed for learning, not just scoring, so you can correct misunderstandings before moving to the next question.

Does the quiz include calculations?

Yes. The free set includes a balanced mix of conceptual questions, applied scenarios and short calculations. The goal is to help you experience several common CQE question styles.

Is my score on this quiz enough to determine whether I am ready?

No single 20-question quiz can confirm full exam readiness. Use it as an initial diagnostic, then assess yourself across larger question sets covering the complete Body of Knowledge.

What is included in the full CQE practice-question package?

The complete package provides additional CQE-style practice sets with broader Body of Knowledge coverage, detailed explanations and more opportunities to work on calculations, scenarios and commonly confused concepts.

Does purchasing the practice tests include the ASQ examination?

No. These are independent exam-preparation materials. Registration, eligibility review and the official certification examination are handled separately by ASQ.

Q1.A chi-square test of independence is applied to a contingency table with 3 rows and 4 columns.

How many degrees of freedom does the test have?
- A.7
- B.11
- C.6✓ Correct answer
- D.12
Explanation
Degrees of freedom for a contingency table are the product of the reduced dimensions:

$df = (r-1)(c-1) = (3-1)(4-1) = 6$

The value 12 is the number of cells and 11 is the cell count minus one, both of which ignore the marginal constraints.
