Students Use Statistics to Justify Senior Project SelectionAbstract Engineering and technology curriculums typically include senior projects as theculmination of a student’s degree program. Students encounter difficulty during theselection process of the project due to uninformed decisions, lack of a structure, methodor model, or an insufficient understanding of the resources needed to complete theproject. The authors address this issue by introducing the utilization of a statisticalmodel in a senior project course.In the course, students work in teams and propose, design, test and build their seniorproject over the course of two semesters. Previously, teams proposed a set of projectsand then settled on a final selection after consultation among the members and theprofessor. In order to make the selection process more structured, the use of metrics wasimplemented to evaluate alternate project concepts. Students were given a spreadsheettemplate model for the metrics and instructed to adapt the model for their measurements.The metrics were based on parameters that measure man hours estimated, team skillscompatibility, resource availability, team interest correlation and team mission statementand public need alignment. For example, the resource metric measured the availabilityand the relative cost of all major components, hardware, software, and tools. For each metric, the student team specified how it was to be measured. This processincluded the identification of what data was available that could be measured. Data setsutilized included relative cost of the proposed components, sales figures of similarproducts, and consumer satisfaction with similar products. Using a standardizedmaximum overall score for the proposed project, each metric had a weighting assignedby the team. For each data set collected, a data error term was computed and the meanand standard deviation of the overall data error was calculated. The “total alternativeproject score” was computed from the individual metric scores. The results of the utilization of the statistical model indicate an increase in studentsuccess, preparedness, and overall achievement of the outcomes of their degree program.
