NAME=Control Limits
See the "Control Limits" topic.
NAME=LCL (Lower Control Limit)
Lower control limit. This is the lower limit for points plotting below the center level on control charts. The lower control limit is used as a criterion for evaluating whether or not the process is in control. The LCL in Datapage+ is calculated from actual measurement data in the X (upper) portion of Individual and Subgroup Charts.
NAME=Mean
Overall average value of measurements in a sample.
NAME=Nominal
Target value.
NAME=Repeatability
The variation in measurements that occurs when one operator uses the same gage for measuring identical characteristics of the same part. Repeatability can be calculated and analyzed by using the GR&R test type to create a GR&R Report.
NAME=Reproducibility
The variation in the average of measurements made by different operators using the same gage when measuring identical characteristics of the same parts. Reproducibility can be calculated and analyzed by using the GR&R test type to create a GR&R Report.
NAME=Sigma
Standard deviation represented by `sigma`. Sigma is a unit of measure indicating the width or spread of the process distribution.
NAME=Specification Limits
Limits that define the conformance boundaries for a quality characteristic.
NAME=UCL (Upper Control Limit)
Upper control limit. This is the upper limit for points plotting above the center level on control charts. The upper control limit is used as a criterion for evaluating whether or not the process is in control.
NAME=Z-Score
In a Cumulative Probablity Chart, the percentage of observations less than a given value.
