Affinity diagram - correct answer-A tool that helps teams sort verbal data or
ideas into categories for further investigation or evaluation.
Analysis of Variance (ANOVA) - correct answer-A statistical method that
helps identify the sources of variability by comparing their means or
averages; it compares the variation within a sample to the variation
between samples to see if any differences are the result of some
contributing factor or if the differences occur by chance alone.
Attribute data - correct answer-Data that shows whether a result meets a
requirement or not (yes/no, pass/fail).
Cause-and effect Diagram - correct answer-A diagram that shows the
underlying causes of a problem or event; also known as a fishbone
diagram.
Check sheet - correct answer-A structured form or table that lets
practitioners collect and record data in a simple format; by putting marks on
a table or image, team members can track and record information about
the number, time, and location of events or problems.
Common cause variation - correct answer-Variation that occurs as a
natural part of a process. The "noise" in the system.
Control chart - correct answer-A modified run chart that also provides upper
and/or lower limits that a process should not exceed.
Control limits - correct answer-The area composed of three standard
deviations on either side of the centerline, or mean, of a normal distribution
of data plotted on a control chart that reflects the expected variation in the
data. See also specification limits.
Critical path - correct answer-Generally, but not always, the sequence of
schedule activities that determines the duration of the project. It is the
longest path through the project. See also critical path methodology.

CTQ Tree - correct answer-A tree diagram that shows how customer needs
or Critical to Quality characteristics can be quantified and measured.
Design of experiments - correct answer-A method that uses statistical
models to determine which combinations of variables are most likely to lead
to the desired quality results; the method tests multiple factors at once to
see how they interact in producing an outcome.
Early finish dates - correct answer-The early start dates for activities plus
the amount of time that the activities will take.
Early start dates - correct answer-The earliest dates that activities can start,
based on the completion of any predecessor activities.
Failure Mode and Effects Analysis - correct answer-An analytical procedure
in which each potential failure mode in every component of a product is to
determine its effect on the reliability of that component and, by itself or in
combination with other possible failure modes, on the reliability of the
product or system and on the required function of the component; or the
examination of a product (at the system and/or lower levels) for all ways
that a failure may occur. For each potential failure, an estimate is made of
its effect on the total system and of its impact. In addition, a review is
undertaken of the action planned to minimize the probability of failure and
to minimize its effects.
Fishbone Diagram - correct answer-A diagram that shows the underlying
causes of a problem or event; also known as a cause-and-effect diagram.
flowchart - correct answer-A graphical representation of the flow of
information in which symbols are used to represent operations, data,
reports generated, equipment, etc. [CMA].
Histogram - correct answer-A vertical bar chart that shows the distribution
of data across groups or categories.
