The students investigated the number of windows per classroom in their school. They counted windows in 60 classrooms and recorded the results in a frequency table. Most classrooms had either 1, 2, or 3 windows. The mode was 2 windows, the median was 3 windows, and the mean was rounded to 5 windows. The range was 15 windows. The students learned how to collect and analyze data as a team through this investigation of windows in the classrooms.
