Accordingly, one easy way to compare the importance of uncertainty in
the variables is to square the swing and express it as a percentage of the sum
of squares of all the swings. The final column in Figures 6–10 and 6–12 show
this swing. (Technically, the variation for Technical Success for the DiagStatic
New alternative is not a 10/50/90 variation and distorts the overall
uncertainty figures shown in the final column.)
