The "average" distance of the individual observations from the mean.
What is the Standard Deviation?
100
The two types of data that can be plotted on control charts
What are Continuous and Attribute data?
100
The appraisers, the gage, and the sample parts
What are the 3 components of variation?
100
This type of variation is due to a factor that has "slipped" into the process causing unstable or unpredictable variation.
What is Special Cause Variation?
100
This distribution curve is symmetric about its mean (half the values fall on either side of the mean) with the ends (tails) extending out to infinity.
What is the Normal Distribution?
200
The middle of the range of data: half the observations are less than or equal to it and half the observations are greater than or equal to it.
What is the Median?
200
The type of control chart that should be used when continuous data is collected in subgroups and the subgroup size is 8 or less
What is the X bar R chart?
200
When conducting a MSA, we want most of the variation to come from this source
What are the sample parts?
200
Process capability compares the output of a process to this by using capability indices.
What are the Specification Limits?
200
The type of process map that includes information on takt time (demand rate), inventory levels, changeover times, and manpower and also shows the flow of information and materials from the suppliers to the customers.
What is a Value Stream Map?
300
The type of graph that is used to illustrate the relationship between two variables by plotting one against the other
What is a scatterplot?
300
This is 3 standard deviations less than the mean
What is Lower Control Limit?
300
The minimum number of distinct categories required in order for the MSA to be acceptable
What is 5?
300
The upper specification limit minus the lower specification limit
What is the Tolerance?
300
The metric that is generally used when calculating the Sigma performance level for a product or process (hint: answer is NOT Cpk)
What is Defects Per Million Opportunities?
400
The type of graphical summary that includes the outliers, upper and lower whiskers, inter-quartile range box, and median
What is a box plot?
400
The change we would expect to see in the X bar chart when the spread increases but the center remains the same
What is increased variance in the data?
400
This represents the variation that occurs when different appraisers measure the same part with the same device.
What is Reproducibility?
400
The maximum value that Cpk can equal when the Cp = 1.2
What is 1.2?
400
The rolled throughput yield for a process that has a yield of 90% at step 1, 80% at step 2, and 70% at step 3.
What is 50.4%?
500
The value for standard deviation when the sample variance = 36 minutes^2
What is 6 minutes? (Standard deviation is equal to the positive square root of the variance).
500
This is used to chart the number of defects per unit when the subgroup size is variable or constant.
What is the U chart?
500
This tells you how accurate your measurements are through the expected range of the measurements.
What is Linearity?
500
The sigma level that is associated with a process that has a Cpk = 1.33
What is 4 Sigma?
500
The six main legs of a fishbone diagram
What are Man, Methods, Materials, Measurement, Machines, and Environment?
