Abstract. Many text books provide students with copious amounts of data in tables and problems. Rarely are standard deviations included with the values that were, at one point, obtained experimentally. This canbea fundamental flaw in students evaluating data to determine if some chemical or physical parameter plays acritical role in a chemical reaction. Nuclear fusion is a holy grail of science because of its potential impact on society as a source of energy. Cold fusion gripped the scientific community twenty five-years ago but erroneous data discouraged additional research in the field before it started. This experiment, given a minuscule chance of success from the beginning, is a variation on the original experiments by Pons and Fleishman. A high frequency (500 kHz) and high voltage (50 kV) discharge was arced through a D2O solution using Pd electrodes to induce the redox reaction. In evaluating the results, students learn the critical importance of statistics in evaluating tritium counts and deciding whether or not a low energy nuclear reaction involving fusion occurred.
