A plant's overall equipment effectiveness is 65 percent, made up of availability 95 percent, performance 95 percent, and quality 72 percent. Where should attention go?

Quality, as the largest single loss

Availability, since downtime is most visible

Performance, since speed losses are cheapest to fix

All three equally, since they multiply together

Are the questions aligned with the ASQ CMQ/OE 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 CMQ/OE question styles.

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

No single 30-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 CMQ/OE 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 plant's overall equipment effectiveness is 65 percent, made up of availability 95 percent, performance 95 percent, and quality 72 percent.

Where should attention go?
- A.Quality, as the largest single loss✓ Correct answer
- B.Availability, since downtime is most visible
- C.Performance, since speed losses are cheapest to fix
- D.All three equally, since they multiply together
Explanation
The three factors multiply, so the smallest one dominates the result: lifting quality from 72 to 90 percent would raise OEE by more than perfecting both of the others. Treating them as equally important ignores how far each currently sits from 100 percent.
Reference: CMQ/OE BoK IV
Q2.A set of measurements has a mean of 50 and a median of 42.

What does this indicate about the distribution?
- A.It is skewed to the right✓ Correct answer
- B.It is skewed to the left
- C.It is symmetric about the mean
- D.It has two distinct peaks
Explanation
The mean is pulled toward the long tail while the median stays with the bulk of the data, so a mean well above the median means the tail extends to the right. Reversing this relationship is among the most common errors in reading summary statistics.
