Black Belt Six Sigma Exam With Complete Solutions
latin square - EXPLANATION an n x n matrix, procedure for controlling order effects
when it is not possible or necessary to use all the possible orders; limited subset of
orders constructed in a way that each condition appears in every ordinal position and
every condition precedes and follows every other condition once
likert scale - ANSWER scale that uses numbers (5 strongly agree, 4 agree.), focuses on
measuring the direction of an attitude
design alias - ANSWER confused experiment or confounded
robustness approach - ANSWER system(concept) design then parameter design, then
tolerance design
alpha risk - ANSWER determines how much area under a distribution is in the critical
region, type 1 risk
beta risk - ANSWER Beta risk refers to the risk of accepting the null hypothesis when, as
a matter of fact, the alternate hypothesis is true. More specifically, it means stating that
no difference exists when there really is a difference. A statistical test should be
capable of detecting differences that are important to you and beta risk is the
probability (for example 0.10 or 10%) it will not. Beta risk is subjective and set by an
organization or individual making the decision, and it depends on the type of decision
being made. Beta risk is a function of the size of the difference between sample means.
Management of beta risk is through increasing test sample size. Generally, beta risk of
10% is considered acceptable in making decisions.
average loss function(smallest) - ANSWER .
EVOP - ANSWER Evolutionary Operations
plackett and burman non-geometric design - ANSWER they are not fractional factorial
and they are main effects only
degrees of freedom - ANSWER df= n(a) +n(b) -2
