SIX SIGMA GREEN BELT
CERTIFICATION EXAM NEWEST 2025
QUESTIONS AND DETAILED CORRECT
ANSWERS | A+ GRADE
Why would Six Sigma activities prompt a re-analysis of
measuring systems? Correct Answer Variability may be
reduced, requiring more precise measurements
Japanese 5S methodology is created and used for:
Correct Answer Creating a productive work environment
What does OEE stands for? Correct Answer Overall
Equipment Effectiveness
The house of quality is used to translate customer wants
into engineering design variables. The linking or
prioritization of customer wants into engineered values
occurs in which of the following elements? Correct Answer
Relationship matrix
What is the name of the condition if you are running a 7-4
fractional experiment? You know factors A, B, C, D, and E
are independent of each other, but you suspect factors F
and G are not independent. You conducted a small sub-
experiment and discovered a high correlation between
factors F and G. Correct Answer Collinearity
,Most of the modern computer programs can perform an
analysis of experimental residuals. Which of the following
techniques will NOT be employed? Correct Answer
Control Charts
If an experiment has an alias, you could say that the two
factor effects are: Correct Answer Confounded
What types of variation does a process have if it is "in
control"?
Process has assignable causes Correct Answer Process
has random causes only
For 4 factors and 3 levels, the DOE setup has 32 runs.
What type of experiment is being conducted? Correct
Answer Half fractional factorial
Which of the following techniques used in DOE helps you
in identifying pure error? Correct Answer Replication`
A combined calculation of repeatability and reproducibility
using the average and range method produces a ratio of
7.42% of process tolerance. What can be stated about the
7.42% value? Correct Answer The measurement system
is acceptable
In a single factor ANOVA, the assumption of homogeneity
of variances applies to: Correct Answer The variances
within the treatment groups
, A perfect regression model with all points fitting the
regression line has Sum Square of Errors ______ Correct
Answer equal to 0
A QFD template allows the Six Sigma team to learn which
of the following? Correct Answer the most important
customer requirements, the performance of a company
versus competitors, the core area of focus for efforts
What are the six experiments called while performing one
experiment with four repetitions? Correct Answer
replications
If men having high Blood Sugar problems are diagnosed
with Diabetes, with the mean blood sugar level to be at
120 and a standard deviation of 9, and any individual
having greater than 100 Blood Sugar levels can be
diagnosed with Diabetes, what is the probability of
committing a Type II Error? Correct Answer 0.0139
Z = (120-100)/9 = 20/9 = 2.2 Area under 2.2 corresponds
to 0.0139. Thus, the probability of a Type II Error, which is
beta, is 1.39%. Option c is the Correct Answer.
A Six Sigma Green Belt practitioner constructs a control
chart to display a process mean and its outer limits. In
such a chart, what does UCL stand for? Correct Answer
upper control limit
To optimize the response of a process, ideally what
sequence of experimentation should one use? Correct
