Measurement, Environment, Equipment, and Materials are most often
associated with which of the following? - ANSWERS-Categories of
major causes
A Cause and Effect Diagram is _____. - ANSWERS-a tool used to
identify and organize potential root causes
The Cause and Effect Diagram (often called a Fishbone Diagram)
displays _____. - ANSWERS-the many potential causes for a specific
problem or effect and immediately sorts ideas into useful categories
What is the main purpose of using a Cause and Effect Diagram? -
ANSWERS-perform root cause analysis
After establishing a team of Subject Matter Experts who have in-
depth knowledge of the product and process, what are the next three
steps of a Root Cause Analysis process? - ANSWERS-1) Define the
problem in terms of the observed effect, 2) Analyze why and when the
problem happened, 3) Develop a permanent solution to prevent the
problem from reoccurring.
What are the three basic rules of Cause and Effect? - ANSWERS-1)
Everything happens for a reason, 2) Cause and effect are part of a
,continuous chain, 3) An effect can be due to both a cause and a
condition.
Which of the highlighted areas on this Cause and Effect diagram
represents the "effect"? - ANSWERS-Area B
Root cause is... - ANSWERS-the fundamental breakdown or failure of
a process or product which, when resolved and corrected, prevents
recurrence of that failure or problem
Which of the following is most often used with a Cause and Effect
Diagram during problem solving analysis? - ANSWERS-

means? - ANSWERS-2-Sample t-test
Which of the following hypothesis tests is appropriate for use with
discrete data? - ANSWERS-Chi-Square test
In hypothesis testing, which of the following is NOT true regarding a
Type I error? - ANSWERS-Occurs when there really is a difference
but we miss it
,A hypothesis test of means that compares the variance between
groups to the variance within groups is: - ANSWERS-ANOVA
When running a Test of Equal Variance for Normal data, which test
statistic is read when you are comparing several samples? -
ANSWERS-Bartlett's test
If we are working with discrete data and we want to compare three or
more groups of data in categories, the appropriate test is... -

rating indicate? - ANSWERS-How significant the impact of a failure
will be to the customer
, Which of the following activities does a Failure Mode and Effects
Analysis involve? - ANSWERS-Studying how and what potentially
could cause a product or process to fail

ANSWERS-The relative ranking of the risks of failure
Which one of the following represents a more severe risk for a Risk
Priority Number? - ANSWERS-A higher value

Analysis is the preferred method for... - ANSWERS-improving
detection techniques or equipment.
In a Failure Mode and Effects Analysis, what does the DET
(Detection) rating indicate? - ANSWERS-The likelihood that the
current control system will detect the failure mode should it occur
