Students are expected to understand sampling strategies for gathering data to represent the entire population. The strategies covered prior to this activity include simple random sampling, stratified sampling, cluster sampling, and systematic 1 in k sampling.
Students are expected to specifically define the population of interest for the project before deciding on which sampling scheme to use.
This activity was used near the beginning of the term in a class on Engineering Statistics and Design of Experiments for 4th year Biomedical Engineering students and 2nd year Industrial Engineering students. The activity was also used as a team building exercise since the class continued to use team based activities and project assignments.
The Minitab functionalities were introduced through demonstration. MP4 files that go through the steps needed to perform the analysis in Minitab were provided to all students to watch prior to starting the project.
Each team prepared a poster to share with the class at the end of the activity. This gallery walk was beneficial to all the students as they were exposed to other solutions. Comparing the different approaches to the same problem enabled students to think critically about the assumptions and methods they employed.
COVID modifications - Gathering data is difficult in light of COVID and restrictions for student interaction. While COVID limitations are in place, I am providing a database with the screen times of previous students for sampling. This takes away from the reinforcement regarding collecting a sample, but it does allow this activity to continue in light of COVID restrictions.
Instead of posters and Gallery Walks, I have the students create a summary of their work in Power Point. Each team posts their presentation slides complete with speaker notes that detail the points they would have made during a gallery walk to the discussion section of our course management software. Part of the individual grade deliverables is the number of team presentations reviewed and commented upon in the discussion section by each student.
On average, students rate this project on average 8.5 out of 10.
