The purpose of this article is to point out a problem when using percentages for subgroups over time, or for members in a larger group, where the size of the denominator varies and probabilities are being estimated.

This is the second interview in the series.

During the last year or so I've heard a lot of people asking, "How can I calculate B10 life in Minitab?" Despite my being a statistician and an industrial engineer (mind you, one who's never actually been in the field) and having taken a reliability engineering course, I'd never heard of B10 life.
