process variation is acceptable. Variation from 10 to 30% is considered problematic,
and any variation over 30% is unacceptable. - CORRECT ANSWER: In gauge

A. 64. If there are four levels and three factors in a complete factorial design, 64 runs
would be required. The number of required runs is calculated by raising the number of
levels to a power equal to the number of factors. In this case, then, the calculation is
performed 43 = 64. If the complete factorial design had five levels and three factors, the
number of runs would be calculated 53 = 125. - CORRECT ANSWER: How many runs

A. Kurtosis. Kurtosis is the parameter of a statistical distribution related to the sharpness
of the peak. In a normal distribution, where the points resemble the standard bell curve,
the kurtosis value is one. If the peak is sharper, the kurtosis value will be higher than
one; if the peak is less severe; the kurtosis value will be less than one. Central tendency
is the general trend of the data: in an asymmetrical distribution, the median is roughly
equivalent to the central tendency, while in an asymmetrical distribution, the mean is a
better marker. Skewness is basically the difference between the mean and the mode of
a data set. The mode of the data set is the value that appears most often. Finally, the
standard deviation of the data set is the average amount of variation from the mean. -
CORRECT ANSWER: Which parameter of a statistical distribution relates to the
sharpness of its peak?
A) Kurtosis
B) Central tendency
C) Skewness
D) Standard deviation
A. Moving Average Chart - CORRECT ANSWER: After a Belt has put data through the
