Roxy Peck is Emerita Associate Dean of the College of Science and Mathematics and Professor of Statistics Emerita at California Polytechnic State University, San Luis Obispo. A faculty member at Cal Poly from 1979 until 2009, Roxy served for six years as Chair of the Statistics Department before becoming Associate Dean, a position she held for 13 years. She received an M.S. in Mathematics and a Ph.D. in Applied Statistics from the University of California, Riverside. Roxy is nationally known in the area of statistics education, and she was presented with the Lifetime Achievement Award in Statistics Education at the U.S. Conference on Teaching Statistics in 2009. In 2003, she received the American Statistical Association’s Founder’s Award, recognizing her contributions to K–12 and undergraduate statistics education. She is a Fellow of the American Statistical Association and an elected member of the International Statistics Institute. Roxy served for five years as the Chief Reader for the Advanced Placement (AP) Statistics Exam and has chaired the American Statistical Association’s Joint Committee with the National Council of Teachers of Mathematics on Curriculum in Statistics and Probability for Grades K–12 and the Section on Statistics Education. In addition to her texts in introductory statistics, Roxy is also co-editor of “Statistical Case Studies: A Collaboration Between Academe and Industry” and a member of the editorial board for “Statistics: A Guide to the Unknown, 4th Edition.” Outside the classroom, Roxy likes to travel and spends her spare time reading mystery novels. She also collects Navajo rugs and heads to Arizona and New Mexico whenever she can find the time. Catherine Case is a senior lecturer in the statistics department at the University of Georgia. She has experience teaching classes of different sizes (from 6 to 240). She has also taught at levels ranging from high school to graduate school and has taught for many different audiences. She has received multiple awards as an instructor. Dr. Case serves as the editor of Statistics Education Web (STEW), a free online resource that provides peer-reviewed lesson plans for teachers at both the K-12 and the college level. She regularly presents at conferences and workshops and has published several articles about students’ understanding of inference. Dr. Case was also a contributor to the NSF Levels of Conceptual Understanding in Statistics (LOCUS) assessment project and a writer for the ASA Statistical Education of Teachers (SET) document. She enjoys cooking, playing the mandolin and drinking way too much coffee on her screened porch. Her favorite days are the ones she spends with her husband Adam, her son Isaac and her dog Gracie.
