Artillery Targeting And Experimental Design
a: Picking the magnitude of an assay variable ~
b: Artillery targeting
What: A typical scenario for both processes goes like this; A variables' magnitude is picked, 1 short, 1 long and 1 in the middle. The study space is defined by the edges and a middle. A good way to test an assay is to determine the values at the extremes. Likewise with an artillery shot. In theory, the math should get you on the target with one shot. But due to variations in wind speed, humidity and other factors, a little empirical range finding is often required. Hopefully, in both cases, you can hit the target. For some reason, 3 is the magic number.
