State Data Map

  • State Data Map


    Information can be represented in many ways, and this applet allows the user to represent data about the states using colors. The state with the highest data value is darkest; other states are shaded proportionally. Investigate any of the data provided—or enter data of your own!



    • Each state in the map below is shaded a percentage of color proportional to the largest data for any state.
      Using the Population data set, for example, California (population 33,871,648) is shaded at 100%, because it has the greatest population; but Colorado (population 4,301,261) is only shaded at 13%, because 4,301,261 ÷ 33,871,648 ≈ 0.13.
    • Choose a Data Set to view various state data. Alternatively, enter values for each state in the table; then, click Update Map to view the results.
    • The Clear Data button can be used to replace all state data with X's. An X indicates that there is no data entered for that state, and data for that state will not influence the mean or five-number summary. (By contrast, a data value of "0" will influence the measures of center.)
    • Click Hide Map Numbers to remove the data from the map. (The data will still be displayed in the table, however.)
    • Change the color of the shading by selecting a different color from the Map Color pull‑down menu.
