OUTPUT:
The SAS System 3 05:42 Sunday, February 4, 2013
The GLM Procedure
Duncan's Multiple Range Test for y1
NOTE: This test controls the Type I comparisonwise error rate, not the experimentwise error rate.
Alpha 0.05 Error Degrees of Freedom 4 Error Mean Square 0.011605
Number of Means 2 Critical Range .2442
Means with the same letter are not significantly different.
Duncan Grouping Mean N x
A 4.03656 3 2
B 3.40191 3 1
ANALYSIS:
DMRT SHOWS THAT MEANS OF VERIFICATION RUNS (2) ARE SIGNIFICANTLY HIGHER THAN THE OPTIMIZATION RUNS (1)
