- Investigating the Modernity of the University Library: Students work in groups to estimate the number of "new" books in the university library given a "budget" for data collection. They will first develop a sampling method, and then implement it in a pilot study. Students conduct a pilot study using a proportion of their "budget". A pilot study report is used to give students timely feedback on their design, estimation, and writing. The design or estimation strategy may be modified before completing data collection and submitting a final report.
