Cartographic Skills, Lab 2: Statistical Foundation



This is a scatterplot that I created for this lab.  It shows the population growth for two states, Alabama and Alaska.  As you can see from the legend provided, Alabama is represented in blue and Alaska in red.  This graph is useful because it also provides you with an estimated population for the future until 2025.  I created this by using Excel and the scatterplot function.  I placed a linear trendline on the graph for each state, making it easier to see the trend.  A linear trendline (rather than polynomial) worked better for this graph because there are no drastic changes, rather a steady and slight growth.  The equations for each trendline are provided, along with the coefficient of determination.
