ACKNOWLEDGMENTS
With gratitude, we acknowledge the following for their assistance and support:
The Woodrow Wilson National Fellowship Foundation , for getting me (D.H.) started thinking seriously
about statistics.
The participants who attended the College Board workshops—I learned as much from them as they did
from me.
Our AP Statistics classes at Gunn High School in Palo Alto, California, North High School in Sheboygan,
Wisconsin, and University High School in Tucson, Arizona for being willing subjects as we learned to
teach AP Statistics.
Grace Feedson , for giving us the opportunity to write this book.
My family, for their encouragement and patience at my unavailability as I worked through the writing
process (especially Petra, Sophia, and Sammy—the world’s three cutest grandchildren) (D.H.).
