Within the Batch Analysis Web report, the Parameter Analysis Web report allows you to compare statistics between selected parameters across multiple batches.

To view the Parameter Analysis

  1. Search for your saved Batch Analysis.

  2. In the Query Results page, select the desired batches.

You must select at least three batches.

  1. Under Multiple Batch, click the Compare Parameters hyperlink.

  2. In the Batch Parameters dialog box, select the batch parameter(s) you want to analyze.

  1. Click OK.

Using the report

Under the Batch Analysis menu:

  • Click Multiple Selection Mode to switch to multiple selection mode, where you can select more than one parameter. If you are already in Multiple Selection Mode, the link will be Single Selection Mode.

  • Click View Interactive Trend to view a trend report of the selected parameter(s).

  • Click View Variable Statistics to view Variable Statistics Summary report.

Under the List Editor menu:

  • Click Reselect Batches to open the Query Results page where you can change your batch selection.

  • Click Edit Query Properties to open the Analysis Properties dialog box.

  • Click Select Parameters to open the Batch Parameter selection dialog box where you can select different parameters.

Parameter Analysis Toolbar

Click the drop-down list to select a different parameter.

Click the green arrows to scroll backward or forward in time. When you scroll backward, the new time period is calculated by multiplying the current time period by -50%. When you scroll forward, the new time period is calculated by multiplying the current time period by +50%. For example, if your current time period is 10 days, when you scroll back in time, the start date of the new time period will be five days before the start date of the current time period. The length of the new time period will still be 10 days.

When you click the Clock icon, the Analysis Properties dialog box will open with the Time tab active, which is where you can specify a new time period.

Click the Copy icon to copy the selected parameter's information to the Clipboard. You can then paste the information into another program, such as Excel.

Click the Properties icon to open the Analysis Properties dialog box.

Click the History icon to view a history of reports that have been viewed.

Parameter Statistics

Each parameter is listed under the Parameter Statistics tab. For each parameter, the following information is provided:

  • Type: This indicates whether the parameter is a Unit Procedure, Operation, or Phase.

  • Count: This is the number of values for the individual parameter.

  • Average: This is the sum of all values divided by the number of values. In other words, it is the Total/Count.

  • Std: This is the standard deviation.

  • %: This is the Percent Deviation, which is calculated by dividing the standard deviation (Std) by the Average.

  • Minimum: The is the minimum value for the individual parameter.

  • Maximum: This is the maximum value for the individual parameter.

  • Total: This is the sum of all values for the individual parameter.

Procedure Graph

This graph plots the values for the selected parameter over the specified time period. On the X-axis, the mid-point in the time period is plotted along with the start time and end time. Click the button to select a different parameter. To close the dialog box, click the button again.

Process Capability Chart

This histogram shows the number of occurrences of a value for the selected parameter. A normal curve is overlaid as a reference. Green bands indicate the values that are within one sigma, a blue band indicates values that within two sigma and a light red band indicates values that are within three siqma.
