MGSC 485 MIDTERM EXAM 1
What is the purpose of the MSA (Measurement System Analysis) -
ANSWERS-To determine if measurement system can generate
accurate data and if accuracy is adequate to achieve objectives
What are two characteristics of data that must be met for reliability
measuring performance of a process? - ANSWERS-Accuracy and
Percision
What is R&R Measurement System Analysis? - ANSWERS-
Repeatability- same person, same result
Reproduceability- same person, same result, over various people
Kappa Calculations - ANSWERS-Used when attribute data cannot be
transformed into continuous data
Histogram - ANSWERS-A basic statistical tool that graphically shows
the frequency or number of observations of a particular value within
a specified group.
Which distribution has the same mean, median, and mode? -
ANSWERS-Normal distribution
, What types of distributions are the following (discrete or
continuous)? Normal, Poisson, Exponential, Binomial, Beta -
ANSWERS-Normal, Exponential, Beta are continuous.
Poisson and Binomial are discrete.
What is the skewness of: Slanting of a curve with a peak to the left of
center line? - ANSWERS-Positive skewness; skewed to the right.
What is the skewness of: Slanting of a curve with a peak to the right
of center line? - ANSWERS-negative skewness; skewed to the left
Run - ANSWERS-series of consecutive points that do not cross the
median
Kano analysis - ANSWERS-provides better understanding of
customers needs, wants, and values of a product or service
CTQ tree - ANSWERS-translates broad customer requirements into
specific CTQ requirements
swim lane diagram - ANSWERS-emphasizes WHO does what
spaghetti diagram - ANSWERS-depicts the physical flow of work or
material in a process
