Tabletop Hockey Meets Goals for Teaching Experimental Design Taken from Newsletter Vol. 26, No. 3
Abstract: The paper describes Tabletop Hockey Experiments where the response variable is the distance traveled by a puck, and it introduces an illustrative two-level factorial experimental design. Moreover, the power of these experiments is that the results are invariably influenced by interactions of factors. Thus, the experimental designs are superior to the traditional one-factor-a-time (OFAT) approach. The students should have access to a computer and statistical software with tools for design and analysis of experiments. Although the results will vary for different teams, almost everyone reveals an interaction between shot type and stick length. In addition, the paper provides links to other interesting experiments.
