Thanks for the link, Jay, I'm going to have to check that out.
I spent a year contracting for a state education administration, developing a system that fed their student annual test performance statistics into No Child Left Behind's data store. Very interesting work. Lots of the data sets were broken down by age or grade, ethnicity, gender, fairly standard stuff for statistical analysis. There was a requirement that if there were 1-4 people in a particular segment, I had to report the number of kids in that group as 5, as otherwise it would be fairly easy to specifically identify the student. Even five is a low number for some school populations, but that's the way it was.
As a result, some data sets would show a different number of students than was reported in the total student counts for the school.
I never review books on Amazon and only rarely on IMDB, now I think I'll make it a point not to! :ermm:
