Runs Tests for Control Chart

Click the Runs tests button on the Specs tab of the Variable Control Chart results dialog box to display the Runs Tests for Control Chart dialog box. Use this dialog box to select which Runs tests to compute. For a description of these tests and their interpretation, refer to the Introductory Overview, or to AT&T (1959), Nelson (1984, 1985), Grant and Leavenworth (1980), or Shirland (1993).  

Note that, by default, the program will not compute the runs test for R and S charts. To compute these tests, select the Compute tests for R/S (variability) charts check box If this check box is not selected, runs tests will not be computed (or checked for Alarms, etc.) for R (MR) and S charts.
