I've had a couple requests to add the "Triola vector" to my matrix of
stats. textbooks. Since the requests came from "family", I tried to
oblige. The vector

T4 1 1 0 0 0

is close to the origin.

However, I was really not trying to get into the reviewing business.
What I wanted was to provide a simple, crude test that could be
applied by anyone to a potential textbook, i.e., I wanted YOU to do
the counting, not ME!

To that end, I should have added a little more detail about how I
counted, though it is more important that you count consistently than
just as I did. I counted PAGES referenced; 142-144 counted as three
pages. If a topic got subheadings, I counted multiple references to
the same page, e.g., I counted

outliers
real bad, 162
not so bad, 162
hardly worth mentioning, 163

as 3 page references. Remember, I was trying to get a handle on the
importance accorded these topics, and I felt multiple consecutive
pages, or an index listing with subheadings, both indicated high
importance for the topic.

I should also note that the numbers after the abbreviations for the
books indicated editions. I did not have the latest editions of
Johnson or Triola because I won't take them when publisher's
representatives offer them. More recent editions might rate higher,
but I would be very concerned about improvements which are merely
cosmetic. The counts are just symptoms of something much deeper --
two (note the data are bimodal) very different conceptions as to the
basic nature of statistics. Indeed, the whole point of the exercise
was to get a quick measure of which side of this dichotomy a book
inhabited.
