Timeline: 3 class periods
This assignment asked students to keep track of water use in their home for an evening. The students completed a small data collection assignment at home. When the class met back together the data was compiled into a large group so that individual student information was hidden.
The idea was introduced on the first day and student questions were answered. They then took the data collection sheet home and had three evenings to get the data collected with their family. They then returned the data sheets to me and I compiled the numbers into a larger spreadsheet. Our second class period included a short discussion about the challenges in the data collection process and what possible statistics could be done using the data. The third and final class period was the most important, where we had the larger data set and we were able to construct confidence intervals and do hypothesis testing using the class data.
