Rule Status

Note: Only point data is evaluated against SPC rules. Data inserted or edited is not evaluated against SPC rules unless the data is on the last line of the Data Entry dialog box.

Set SPC rules to any of the following status:

Note: Rules set to reject or warn are the active rules for the test.

• Reject

  UnityWeb™ rejects data violating the SPC rule and excludes it from the summary statistic calculations. The rule violated appears in the Rules column on the Data Entry dialog box and on intralaboratory charts and reports.

• Warn

  UnityWeb™ accepts data violating the SPC rule. The rule violated appears in the Rules column on the Data Entry dialog box and on intralaboratory charts and reports.

• Off

  UnityWeb™ ignores the rule when evaluating data points.

UnityWeb™ begins evaluating point data against SPC rules with a status of reject or warn after the test has the number of data points specified on the Settings tab of the Rules/Settings dialog box. See "Set SPC Rules" for more information.

Note: Twenty data points is generally considered the minimum for statistical significance and therefore is the default number used in the software. Specify a fixed mean and SD to have rule evaluation begin immediately. See "Use a Fixed Mean and Fixed SD with SPC Rules" for more information.
