Range Measures
You can use range measures to obtain statistical feedback about any existing measure. Ranges dynamically calculate the maximum, minimum, average, or variation characteristics of any measure.
Range Measure Characteristic Descriptions
The following table describes the characteristics that range measures provide. For information on the conventions used, see Conventions.
The measure: | Description: | Definition/Formula: |
|---|---|---|
Average | Arithmetic mean of current set of measured data. |  |
Minimum | Minimum value in the current set of measured data. | Min (M1, M2, ..., Mn) |
Maximum | Maximum value in the current set of measured data. | Max (M1, M2, ..., Mn) |
Variation | Difference between the maximum and minimum value in the current set of measured data. | Maximum - Minimum |
To create a range measure:
1. Click the Design Exploration tab. From the Measures container, click the Range measure tool 
.
.or
(Classic interface) From the Build menu, point to Measure, point to Range, and then select New.
The Range Measure dialog box appears.
2. In the Name text box, enter a name for the measure.
3. Set Type to the range characteristic to measure.
4. In the Of Measure text box, enter an existing, predefined measure to analyze.
6. Select OK.
