Experiment Design and Conduct The previous hypotheses will be tested through different measures that we will collect from subjects during the experiment. In a general way, measures belong to two subject groups: Those who perform a task in pairs and those who perform it individually. With these measures, we will perform statistical analyses given an experimental design. At the beginning of the DOE course, we decided to conduct the experiment at the midterm (semester) in order to students had certain knowledge of DOE and that they had sufficient time to write a report before the semester ended. The experimental design to use was selected according to the designs listed in the DOE course syllabus. Specifically, we chose the Latin square design because it was scheduled in the course syllabus at midterm, just a few days before the experiment was conducted. Authors: (1) Omar S.
