B: Histogram chart
C: Fish Bone graph
D: Pareto chart - answerD: Pareto chart
A control chart helps identify whether the process is:
A: Stable
B: Capable
C: Correlated
D: Prediction - answerA: Stable
What kind of graph would help analyze the stability of non-parametric distribution of
data points?
A: P-Chart
B: I-MR Chart
C: C-Chart
D: Box plot - answerD: Box plot
If the sample value of of sub group size is n=1, choose the appropriate type of graph for
outlier analysis:
A: P-Chart
B: I-MR chart
C: C-Chart
D: NP-Chart - answerB: I=MR chart
If special causes are assigned in the process variations, then the UCL and LCL would
be recomputed w/o removing these outliers (T/F)? - answerFalse
All the data points lie within UCL and LCL and 10/11 data points on one side of the
mean value (central limit) indicate whether the process is having:
A: Special causes
B: Common causes
C: Assignable causes
D: Outliers - answerB: Common causes

to interpret for stable process?
A: 5 rules
B: 7 rules
C: 6 rules
D: 8 rules - answer7 rules (why though?)

indicate what type of distributions would be suited for understanding the process
behavior?
A: Poisson
B: Binomial
C: Normal
D: Exponential - answerC: Normal distribution
The area under the curve value is 1, then the mean/median/mode values would be the
same (T/F) - answerTrue
(blank) can be measured against a benchmark in a process
A: Performance
