ab: Summary: This article describes a collaborative learning experience in
experimental design that closely approximates what practicing
statisticians and researchers in applied science experience during
consulting. Statistics majors worked with a teaching assistant from the
chemistry department to conduct a series of experiments characterizing
the variation in measured voltage output of Smestad and Gratzel’s
nanocrystaline titanium dioxide (TiO2) solar cells. These solar cells
can be constructed easily in a laboratory, and they are reported to
produce an open circuit voltage in direct sunlight of 0.3 to 0.5V.
Statistics students planned a series of experiments as part of an
experimental design class, and the chemistry TA performed the
experiments in the lab where the statistics students could observe. The
students wrote a description of what they did and the results. From the
students’ comments about what they learned from this experience, it
appears that this type of exercise could be very beneficial in training
future consulting statisticians and scientists or technologists who
will use experimentation in their work. (Contains 8 figures and 5
tables.) (ERIC)
