Exam 11: Statistically Based Quality Improvement for Variables

Interlinking is useful in helping to identify causal relationships between variables.

Samples can be ________ according to time or according to sequence.

A ________ subgroup is a group of data that is logically homogeneous.

________ is the probability that a good product will be rejected.

The ________ reflects a population distribution.

Process ________ means that the variation we observe in the process is random variation and not nonrandom variation.

Nonrandom variation is centered on a mean and occurs with a consistent amount of dispersion.

________ is a decision-making skill demonstrated by the ability to draw conclusions based on data.

Describe x charts and R charts. List and describe the basic components of each.

One of the reasons that statistical tools are deemed to fail is because people have a poor understanding of the scientific method.

________ are often used in monitoring the production of silicon chips for computers.

Describe the purpose of an s chart.

A ________ is used when data are geometrically distributed.

________ is the probability that a nonconforming product will be available for sale.

The first step in developing process control charts is to identify critical product characteristics.

Which of the following is not one of the alternative names for one hundred percent samples?

Quality practitioners should not compare process chart limits with product specifications.

Producer's risk is the probability that a nonconforming product will be available for sale.

Process stability means that the variation observed in the process is nonrandom variation and not random variation.

Random variation results from an event such as a shift in a process mean or some unexpected occurrence.
