MAT 510-MIDTERM EXAM

Question 1





Improvement
is needed for an organization to survive because:




Question 2





Understanding
variation is important because variation:







Question 3

 









Which
of the following are principles of Statistical Thinking?
 
      Question 4
 








The
standard deviation is:













Question 5









Process
improvement activities typically include:







Question 6









In
Figure 2.11, Coach Hau presented data showing where goals were scored on
crosses. This produced unexpected result, in terms of where the goals came
from, and helped his team determine an effective strategy on free kicks. This
is an example of what principle of statistical thinking?







Question 7









Box,
Hunter, and Hunter are quoted in this chapter as stating: “Data have no
meaning in themselves; they are meaningful only in relation to a conceptual
model of the phenomenon studied.” This critical point is related to which of
the following principles of statistical thinking?







Question 8









The
fact that processes tend to be dynamic, rather than static, is a key
principle of statistical thinking. Which of the following is a natural
consequence of this fact?







Question 9









Figure
2.16 shows a chart of the Dow Jones Industrial Average from 1990 through
2011. This plot reveals some obvious change points, such as the 2008
financial collapse, and some unexplainable short-term variation. Assuming
that these are the only sources of variation in this plot, what source of
variation is NOT visible in the plot?







 

Question 10









In
the advertising case study, the unexpected “V” shaped pattern in the plot of
advertising dollars versus sales indicated what?







Question 11









Figure
2.15 displays a model of the statistics discipline, showing the relationship
between statistical thinking, statistical engineering, and statistical
methods and tools. Which of the following is a principle illustrated by this
model?







Question 12

 









What
is tool that can be used to detect the structure variation?







Question 13









Service
and non-manufacturing processes:







Question 14









The
primary goal of process mapping is to:







Question 15

 









Improving
the quality of process measurements is:







Question 16

 









Refer
to Figure 3.21 and choose the correct statement for the measurements







Question 17

 









We
measure, monitor and improve process cycle time because:







Question 18

 









Processes
are important because:







 

Question 19

 









Process
complexity is important because complex processes:







Question 20

 









Use
of subject matter knowledge is a key aspect of the Statistical Thinking
Strategy discussed in Chapter 2. For which of the following case studies in
Chapter 4 was this principle NOT clearly applied?







Question 21

 









The
Problem Solving Framework begins with a “Document the Problem” phase. The
Process Improvement Framework does not begin this way, but rather begins with
an “Understand the Process phase.” Which of the following are valid reasons
for this difference?







Question 22

 









We
learned in Chapter 2 that most processes are dynamic in nature, and therefore
the time dimension is often a critical consideration in process improvement.
For which of the case studies in Chapter 4 was plotting data over time NOT
critical to success?







 

Question 23

 









Suppose
the Problem Solving Framework were used to attack a problem where the process
in question was inherently stable. Which of the following would be a likely
result of this effort?







 

Question 24

 









Suppose
a DMAIC Framework were used to attack a problem where the process in question
was inherently stable. Which of the following would be a likely result of
this effort?







Question 25

 









Which
of the following are accurate statements about the relationship between the
Process Improvement Framework (PIF) and the Problem Solving Framework (PSF)?
