Students will create a scatter plot of the world population for the years 1950 through 2050. The United Nations Population Division data will allow students
to explore real-life data that will be modeled by a logistic function. Students will have the opportunity to explore the end behavior of this model and explain what this means about the world population estimates. The derivative will be used to explore when the world population increased most rapidly during this time period.
