Return to Our Roots: Raising Radishes To Teach Experimental Design.
Stallings, William M.
To provide practice in making design decisions, collecting and analyzing data, and writing and documenting results, a professor of statistics has his graduate students in statistics and research methodology classes design and perform an experiment on the effects of fertilizers on the growth of radishes. This project has been required of students in a graduate-level class in statistics and design in each of the last three times the professor has taught the course. Students in the class are typically working toward advanced degrees in education or nursing, and many have weak backgrounds in science. An informal evaluation based on 7 written comments from student course evaluations and 32 student reports indicates that students learn from the project and meet at least the minimal expectations, although only a few go beyond the minimal statistical requirements. Several changes are planned to enhance the project as a teaching tool. Two tables present procedural details and the frequency of design and treatment decision. (SLD)
