This was an activity where I had the students create their own data for scatter plots. The activity is where you split the students into 4 groups and in each group they hold hands and you put 1 hula hoop between the two students arms. They then try to see how fast they can move the hula hoop all the way around the circle. They record their groups data. We usually do this activity outside. Once back inside we record the rest of the classes data and graph it.
