There are sometimes 3 columns on a datasheet which may contain min, nom, and max values. Like Vds for example.
 Is there any probability tacitly assigned to the values? I know that nominal is the average, and I assume that the value lies between the two middle one standard deviation points.
 1. Is that a valid assumption?
 2. Is the min between one and two standard deviations down from the mean?

Min and Max are "guaranteed" limits (as much as anything can be "guaranteed").
Typ(ical) is where the *process* tends to produce the most yield.
That can change, over time. But, it will always be constrained by [min,max].
