I have a set of sample results and controls for 3 levels. Control values like : 0.8; 1.7; 2.5 sample values: 0.45, .75, 0.9, 1.2, 1.23, 1.35, 1.45, 1.55, 1.54, 1.78, 1.89, 1.98, 2.01, 2.33, 2.45, 2.65, 2.8, 3.0
In practics, I simply based on each sample data point position relative to control in Excel chart to classify them to a control group. I wonder if there is any statistical parameter I can compute to support my claim that 1.23 should be more like control of 0.8, but not control of 1.7? is there some kind of likelihood or probabilty to be computed? Seems silly, but it does happen a lot in reality. . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
