If your control chart shows points outside 3 sigma control limits, your process is said to be this.
What is unstable or out of control?
100
The baseline assumption of a hypothesis test has this special name.
What is the null hypothesis?
100
In a designed experiment, this term denotes a variable controlled by the experimenter.
What is a Factor?
100
This diagram shows dependencies and timelines for all tasks in a project, representing task durations by bar lengths, and can also be used to assess project progress.
What is a Gantt chart?
100
Mean defects per unit is a simple process capability index for this type of data.
What is attribute data?
200
This type of control chart would be used when analyzing the percentage defective of standard lots of 10 gears.
What is an np chart?
200
This type of complex hypothesis tests are used when dealing with populations of unknown distribution.
What are non-parametric tests?
200
This type of plot shows the effects of one factor on the response variable.
What is a main effects plot?
200
The upper portion of a value stream map generally shows the flow of this.
What is data or information?
200
The difference between Cp and Cpk is that Cpk accounts for this feature of the data distribution.
What is skew?
300
This control chart is best used when variables data are slow moving.
What is an I-MR chart?
300
This hypothesis test would be used to compare the "before and after" results from a process change.
What is a Paired t test?
300
This term denotes a complete set of levels for each variable in the experimenter's control.
What is a treatment combination?
300
If you see a huge pile of drive units near the shipping dock, you can expect that Kiva has fallen prey to this waste.
What is overproduction?
300
An example of this measurement system error would be crushing a soft ball with calipers so that it gets smaller with each measurement.
What is altering the sample during the study?
400
This is the typical subgroup size for X-bar R and X-bar S charts.
What is 3-5?
400
This type of error reflects the possibility that the baseline hypothesis would be rejected when it is actually true.
What is type I or alpha error?
400
For your experiment to be valid, these three things are required.
What are adequate measurement systems, stable processes, and statistically controlled experimental errors/residuals?
400
This method for ranking customer requirements gives each participant a set number of points to distribute among various requirements.
What is multivoting?
400
This distribution represents the chance of having a certain percentage of failed units given a sample size and a nominal failure rate.
What is the binomial distribution?
500
This Western Electric engineer created the set of 8 rules used to test for special cause on control charts.
Who was Lloyd Nelson?
500
This distribution would be used to test "Goodness of Fit".
What is Chi-Square?
500
This experimental design allows fewer runs while analyzing the effect of multiple factors, but runs the risk of confounding.
What is a fractional factorial design?
500
This process performance parameter corresponds to the "Occurrence" ranking in the FMEA.
What is Ppk?
500
If the yield of bench test is 50% and the yield of certification test is 25%, this is the probability of a unit passing both tests.
