Popcorn Statistics


This hands-on exercise using individual packages of popcorn to repackages basic concepts of statistics. Dr. Steve Carpenter from the University of Wisconsin, followed by Dr. Gary Lamberti from the University of Notre Dame, developed an example to test a particular statistical design using popcorn. Having taken Biostatistics from Dr. Lamberti 15 years ago, the ideas clearly stuck in my mind. I used the single design as a starting point to develop a larger, longer and more comprehensive version of Popcorn Statistics. An article summarizing this exercise will soon appear in The ASLO Bulletin. If you have any questions about the material on this website or the article, please feel free to email me, Dr. Romi Burks
