1. 1An ASQ certification holder finds that a published process summary omits several unfavorable measurements. Which response follows the ASQ Code of Ethics?

   1. A. Keep the summary because the favorable measurements are accurate.
   2. B. Disclose the omitted measurements and correct the misleading summary.
   3. C. Retain the summary but share the omissions only with a colleague.
   4. D. Replace the unfavorable measurements with the process target values.

   Answer: B

   Explanation: The code states, "Be truthful and transparent in all professional interactions and activities." Correcting the selective reporting restores transparency; retaining or substituting data would misrepresent process performance.

2. 2A team has planned a change to a service process and wants to try it on a limited scale before wider adoption. Which PDCA step includes this trial?

   1. A. Plan
   2. B. Do
   3. C. Check
   4. D. Act

   Answer: B

   Explanation: ASQ states, "Do: Test the change. Carry out a small-scale study." The trial implements the planned test; reviewing its results is Check, and adopting changes based on learning is Act.

3. 3Five observed processing times are 4, 5, 5, 6, and 10 minutes. What is their arithmetic mean?

   1. A. 5 minutes
   2. B. 6 minutes
   3. C. 7.5 minutes
   4. D. 10 minutes

   Answer: B

   Explanation: NIST defines the mean as "the sum of the data points divided by the number of data points." The sum is 30 minutes, and 30/5 = 6 minutes. Five is the median and mode, 7.5 results from dividing by four, and ten is the maximum.

4. 4Within one company, the payroll department receives approved time records from production supervisors. In this exchange, what is payroll's relationship to the supervisors' output?

   1. A. External supplier
   2. B. Internal customer
   3. C. Internal supplier
   4. D. External customer

   Answer: B

   Explanation: ASQ defines an internal customer as "The recipient (person or department) within an organization of another person’s or department’s output". Payroll receives the records within the same company, making it the internal customer in this exchange.

   Reference: ASQ Quality Glossary — I / Internal customer

5. 5A team has repaired the units affected by a recurring defect. What additional objective distinguishes corrective action from repairing those units?

   1. A. Increasing the number of repaired units recorded in the current lot
   2. B. Eliminating the causes of the defect to prevent recurrence
   3. C. Moving the affected units to a different inspection station
   4. D. Changing the defect's reporting category without changing the process

   Answer: B

   Explanation: ASQ states, "Corrective action is action taken to eliminate the causes of an existing nonconformity, defect, or other undesirable situation in order to prevent recurrence". Repair addresses affected units; corrective action addresses the causes that would otherwise generate the defect again.

6. 6A quality analyst is asked to independently approve a specialized technical evaluation outside the analyst's training and competence. Which action is consistent with the ASQ Code of Ethics?

   1. A. Approve it after comparing the report format with an earlier evaluation.
   2. B. Approve it if the requester accepts responsibility for technical errors.
   3. C. Sign it with a note that the assignment was completed under time pressure.
   4. D. Explain the limitation and seek a qualified person for the technical evaluation.

   Answer: D

   Explanation: ASQ requires professionals to "undertake assignments only in your areas of competence, expertise, and training." Referral respects that boundary. A familiar format, a waiver, or time pressure does not establish competence.

   Reference: ASQ Code of Ethics — Act with Integrity and Honesty / competence

7. 7After a pilot test, a team compares the observed results with its expectations and identifies what it learned. Which PDCA step is the team performing?

   1. A. Act — incorporate learning into subsequent changes
   2. B. Plan — recognize an opportunity and plan the change
   3. C. Do — conduct the limited trial of the planned change
   4. D. Check — analyze the trial results and identify learning

   Answer: D

   Explanation: The procedure states, "Check: Review the test, analyze the results, and identify what you’ve learned." The team is interpreting evidence rather than planning, running the test, or deploying the resulting change.

8. 8Most customer waiting times are short, but a few are extremely long. An analyst wants a central-location measure less affected by those extreme waits than the arithmetic mean. Which measure fits?

   1. A. Maximum
   2. B. Mid-range
   3. C. Range
   4. D. Median

   Answer: D

   Explanation: NIST explains, "these extreme values do not distort the median since the median is based on ranks." The median locates the middle observation. Maximum, mid-range, and range depend directly on extreme values; range is also a spread measure rather than a central value.

   Reference: NIST/SEMATECH e-Handbook: Measures of Location — Why Different Measures / Cauchy Distribution discussion of extreme values

9. 9An independent laboratory provides test results as an input to a manufacturer's release process. Relative to the manufacturer, which role does the laboratory perform in this exchange?

   1. A. An internal customer receiving a departmental output
   2. B. An external customer receiving the manufacturer's output
   3. C. An internal supplier providing input within the manufacturer
   4. D. An external supplier providing input from another organization

   Answer: D

   Explanation: ASQ defines a supplier as "A source of materials, service or information input provided to a process." The laboratory supplies information and is outside the manufacturer’s organization, so it is an external supplier rather than the recipient of the manufacturing process’s output.

   Reference: ASQ Quality Glossary — S / Supplier

10. 10While using the five whys, a team reaches its fifth question but has not yet identified a supported root cause. How should the team treat the number five?

    1. A. As a mandatory stopping point, even if only symptoms have been found
    2. B. As a minimum question count, even if a supported cause is found earlier
    3. C. As proof that the fifth answer is the root cause without further evidence
    4. D. As a guide; more or fewer questions may be needed to reach the cause

    Answer: D

    Explanation: ASQ states, "It may take less or more than five times to reach the root cause or solution." Five is neither a mandatory maximum nor a mandatory minimum. A supported causal explanation, rather than a numbered answer alone, determines whether investigation has reached a root cause.
