The key variables related to this question are the Number of Eyelets on a pair of shoes and the Number of Pairs of Shoes.
Students first count eyelets within the classroom, record data and create bar graphs from the table.
In addition they compute the mean, median and mode of the data gathered. From this initial information, students are asked to make predictions about and analyze the results from other classrooms in their school and then from around the world. Included in their analysis will be the impact that weather and climate might have on the types of shoes other students wear. In other words, students will come to realize that other variables, some known and unknown, might affect the results of the data.
