Data Analysis, Probability, and Statistics for Teachers

This book (to be published by Key College Publishing in late 2006) is a data analysis and probability
textbook for prospective and in-service Middle School and High School teachers. The National Council of
Teachers in Mathematics (NCTM) has recently established standards in data analysis and probability to
be taught to all students from grades K-12. This text is designed to teach the prospective teachers basic
concepts in probability and statistics so they have the background to teach the content listed in the NCTM
standards. The basic concepts in data analysis and probability will be taught by means of discovery and
group interaction on directed activities, both of the hands-on and technology varieties. Technology is
implemented by means of the software Fathom, Tinkerplots and the TI 84-Plus graphing calculator.
