ASQ CQA CERTIFICATION EXAM
SCRIPT 2026 COMPLETE QUESTIONS
ACCURATE ANSWERS
◉ Histograms. Answer: Vertical bar chart of a frequency distribution
used to show number of times a given discrete piece of information
occurs in the data set
◉ Bell-Shaped Distribution. Answer: Normal distribution in Histograms
Deviations may indicate presence of complicating factors or outside
influences - should be investigated but are not necessarily bad
◉ Plateau. Answer: Distribution in histograms
Flat top with no distinct peak and slight tails on either side
May be a result of many different bell-shaped distributions with centers
spread evenly throughout the range of data
May sometimes naturally occur, or may have several overlapping
populations causing a plateau, or there is a problem with measurement
system
◉ Comb. Answer: Distribution in histograms
High and low values alternating in a regular fashion
,o Error in measurement, in the way data was grouped, or systematic bias
in how data was rounded
◉ Skewed. Answer: Distribution in histograms
o Asymmetrical shape in which the peak is off center in the range, and
tails off sharply on one side but gently on the other.
o Negatively skewed: tails towards left
o Positively skewed: tails towards right
o If you have a hard boundary, and data piles up against that boundary
but drags on toward the limit
o Naturally occurring phenomenon
◉ Truncated. Answer: Distribution in histograms
o Asymmetrical shape in which the peak is at or near the edge of the
range, and distribution ends very abruptly on one side but tails off gently
on the other.
o May indicate a problem - Ex, data was removed from the set
◉ Isolated-peakd. Answer: Distribution in histograms
o Small separate group of data in addition to the larger distribution.
Similar to double-peaked but the short bell shape indicates something
that doesn't happen very often.
◉ Edge-peaked. Answer: Distribution in histograms
,o Large peak appended to an otherwise smooth distribution. Similar to
Comb in that an error was probably made in the data.
◉ SIPOC. Answer: supplier-input-process-output-customer
· Cannot improve a process without understanding how it functions from
a process management perspective
◉ PDCA. Answer: Plan-Do-Check-Act
· Plan: identify opportunity for improvement
o Define activities to be performed: data collection, RCA, stakeholder
meeting,
· Do: perform a trial run to see if project is running in the right direction
or not
· Check: compile and analyze results from Do stage - readjust if
necessary
o May change the plan, adopt it in procedure, abandon the idea,
changing the scope, etc. then starting over
· Act: Implement actions / OR Adjust plan and take another trip
o Must monitor results
◉ RCA 7 Step problem-solving model. Answer: 1. Identify the problem
- use data analysis tools such as flowcharts, etc.
2. List possible root causes - all invested groups should weigh in
3. Search out/investigate the most likely root or probable cause
4. Identify potential solutions
, 5. Select and implement a solution
6. Followup to evaluate effectiveness of the solution
a. Control charts, frequency distributions can help show effectiveness
7. Standardize the process if it was proven to be successful
a. Revise procedures, construct production device, etc.
◉ Six Sigma. Answer: · Statistical methodology that focuses on
reducing variation and defects and mistake-proofing a process
· 6sigma:
o Measure variation in products relative to specifications
o Operating at a 6sigma level indicates products are 99.9997% defect
free
o To what extent a product/process varies from perfection
o Process for structuring improvement goals by using DMAIC
◉ DMAIC. Answer: o Define: identify requirements, set the goals for
the process improvement project
§ Team charter prepared
§ Problem statement, scope, goals, responsibilities, timeline
§ Collect VOC
§ Tollgate review
o Measure: baseline the current situation
§ Gathers data from targeted process to establish baseline performance
§ Process map current state, understand what is happening
