A chemist is interested in the effects of five different catalysts (A, B, C, D, and E) on the reaction time of a chemical process. There are five batches of new material (1, 2, 3, 4, and 5). She decides to study the effect of each catalyst on each material for five days (1, 2, 3, 4, and 5). Construct a Latin square design for this experiment.
