Then there must be more versions of that text than the one you with  
which you are acquainted with. The first page of Contents of this pdf  
file:

http://fisher.stat.wmich.edu/joe/Stat666/book/book.pdf

# which bears your advisor's name as co-author and is presumably  
sitting on his website

...has an entry:

1.9 Ranked Set  
Sampling . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .  
53

And there VERY DEFINITELY IS a 4 page section that bears that title in  
the body of the text. Which leads me to ask: How often do you talk to  
your advisor?
